WASHINGTON — Mitt Romney scored a hardwon, home-state triumph in Michigan and powered to victory Tuesday night in Arizona, gaining a two-state primary sweep over Rick Santorum and momentum in the most-turbulent Republican presidential race in a generation.
“We didn’t win by a lot, but we won by enough,” Romney told cheering supporters in Michigan. He also tweeted: “I take great pride in my Michigan roots, and am humbled to have received so much support here these past few weeks.
“On to the March contests,” he said, looking ahead to next Tuesday’s races that could go a long way toward determining the Republican who will take on President Barack Obama this fall.
Santorum was already campaigning in Ohio, one of next week’s states, when the verdict arrived from Michigan.
“A month ago they didn’t know who we are, but they do now,” he told his own supporters, vowing to stay the conservative course he has set.
The two other candidates, Newt Gingrich and Ron Paul, made little effort in either Michigan or Arizona, pointing instead to next week’s collection of contests in all corners of the country.
Romney’s Arizona triumph came in a race that was scarcely contested, and he pocketed all of the 29 Republican National Convention delegates at stake in the winner-take-all state.
Michigan, however, was a hard-fought and expensive battle in Romney’s home state that he could ill afford to lose and Santorum made every effort to win.
Returns from 92 percent of Michigan’s precincts showed Romney, with 382,340 votes, at 41 percent and Santorum, with 351,370 votes, at 38 percent. Paul, with 109,016 votes, was winning 12 percent of the vote to 7 percent for Gingrich, who had 60,681.
In Arizona, with votes counted from 73 percent of the precincts, Romney, with 206,626 votes, had 47 percent; Santorum, with 113,927 votes, had 26 percent; Gingrich, at 71,001 votes, had 16 percent; and Paul, with 36,887 votes, had 8 percent.
In Michigan, 30 delegates were apportioned according to the popular vote. Two were set aside for the winner of each of the state’s 14 congressional districts. The remaining two delegates were likely to be divided between the top finishers in the statewide vote.
With his victory in Arizona, Romney had 152 delegates, according to The AP’s count, compared to 72 for Santorum, 32 for Gingrich and 19 for Paul. It takes 1,144 to win the nomination at the Republican National Convention in Tampa, Fla., in the summer.
In interviews as they left their polling places, Michigan voters expressed a notable lack of enthusiasm about their choices. Just 45 percent said they strongly favored the candidate they voted for, while 38 percent expressed reservations and 16 percent said they made the choice they did because they disliked the alternatives.
Along with an improving economy, the long and increasingly harsh campaign, in which Gingrich and Santorum have challenged Romney as insufficiently conservative, has prompted some officials to express concern about the party’s chances of defeating Obama in the fall.
Romney signaled he intends to stick to his core campaign message of fixing the economy and reducing unemployment in a nation still recovering from the worst recession in decades.
“More jobs, less debt and smaller government — you’re going to hear that” over and over in the states ahead, he said.
Exit polling showed a plurality of Republican voters in Michigan and Arizona saying the most important factor to them in the primaries was that a candidate be able to beat Obama in November. Romney won that group in Michigan and also prevailed among voters in the state who said experience was the quality that mattered most.
Santorum ran particularly well among voters who cited a desire for strong conservatism or strong moral character.
The polls surveyed primary-day, absentee and early voters. Interviews were conducted at 30 polling places in each state. Early results from Arizona’s poll included interviews with 2,535 voters, including 601 absentee or early voters interviewed by phone. In Michigan it was 2,200 interviews including 412 absentee or early voters interviewed by telephone. The margin of sampling error for the Michigan poll was plus or minus 4 percentage points, and it was 3 points in Arizona.
Not even the opening of polls Tuesday ended the squabbling between the two leading Republicans.
Romney accused Santorum of trying to hijack a victory in Michigan by courting Democratic votes through automated telephone calls and suggested his rival was appealing to conservatives by making the kind of “incendiary” statements he would not.
“I’m not willing to light my hair on fire to try and get support,” Romney said. “I am what I am.”
Santorum brushed aside the allegations of hijacking, saying Romney had appealed for support from independents in earlier states.
“We’re going to get voters that we need to be able to win this election. And we’re going to do that here in Michigan today,” Santorum said, referring to blue-collar voters with a history of swinging between the parties.
The exit poll said about 10 percent of the day’s Michigan primary voters were Democrats.
The unexpected clash on Romney’s home field dramatized that two months into the campaign season, after nearly a dozen primaries and caucuses, the Republican race to pick an opponent for Obama remains unpredictable.
Unopposed for renomination, Obama timed a campaign-style appearance before United Auto Workers union members in Washington for the same day as the Michigan primary. Attacking Republicans, he said assertions that union members profited from a taxpayer-paid rescue of the auto industry in 2008 are a “load of you-know-what.”
All of the Republicans running for the White House opposed the bailout, but even in the party’s Michigan primary a survey of voters leaving polling places showed about four in 10 supported it.
Michigan loomed as a key test for Romney as he struggled to reclaim his early standing as front-runner in the race. The first of the industrial battleground states to vote in the nominating campaign, it is also the place where the former Massachusetts governor was born and where he won a primary when he first ran for the party nomination four years ago.
But Santorum, a former Pennsylvania senator, rolled into the state on the strength of surprising victories on Feb. 7 in caucuses in Minnesota and Colorado plus a nonbinding primary in Missouri. He quickly sought to stitch together the same coalition of conservatives and Tea Party activists that carried him to a narrow victory in the Iowa caucuses that opened the campaign nearly two months ago.
The Michigan primary was open to Republicans or any voter who declared he was Republican for the purpose of voting, and there was precedent for an influx of outsiders influencing the outcome.
A dozen years ago, John McCain defeated the heavily favored George W. Bush, relying on the support of Michigan independents and Democrats. Exit polls then showed that Bush won 66 percent of Republican votes, while Mc-Cain won 82 percent of selfdescribed Democrats and 67 percent of independents. Together, the non-Republican voters accounted for more than half the electorate.
In a measure this year of the state’s importance to the battle for the nomination, the two leading candidates and the super political action committees that support them spent about $6 million on television advertisements, and Romney and Santorum spent much of the past 10 days crisscrossing the state in search of support.
Arizona was Romney’s to lose, judging by the behavior of his rivals, who spent little time campaigning in the state and no money advertising on its television airwaves.
There are 40 delegates at stake in Washington caucuses Saturday, followed by 419 next Tuesday, including big state primaries in Ohio and Georgia.
Already, the television advertising wars were under way. Romney and Restore Our Future, the super PAC that supports him, have spent more than $3 million combined on ads in Ohio.
In Michigan, Santorum campaigned heavily for the support of Tea Party activists and other nonestablishment Republicans, appearing in churches at times and often dwelling on social issues. In a string of remarks in the race’s final days, he said Obama was a snob who wanted everyone to attend college, said he nearly threw up over a speech that candidate John F. Kennedy gave in 1960 about the separation of church and state, and said Romney was uniquely unqualified to defeat Obama because the two men shared so much in common on issues such as health care.
The former Massachusetts governor made a play for Tea Party support, too, at a pair of appearances, but for the most part campaigned on his pledge to use his background as a successful businessman to help create jobs and fix the economy. Last week, he issued a call for 20 percent across-theboard cuts in personal incometax rates.
But he was hampered by off-the-cuff comments that reinforced his difficulty in reaching out to struggling voters in a state with 9.3 percent unemployment. He said at one point that his wife drives a couple of Cadillacs, and at another that he was friends with some of the owners of NASCAR teams.
At a rare news conference after the polls opened Tuesday, he conceded that his own mistakes had hurt his campaign.
The primaries in Michigan and Arizona were the first contests since Romney squeaked out a victory over Paul in the Maine caucuses on Feb. 11, a lull of 2 1/2 weeks.
Except for a debate in Arizona last Wednesday and a brief burst of campaigning in the hours before and after, Romney and Santorum focused their time and campaign money on Michigan.
Polls showed Santorum racing to a large advantage after his victories on Feb. 7, before the weight of attack ads by the Romney-aligned super PAC and the candidate himself began to narrow and finally erase the gap in many surveys.
