Romney Rounds on Obama with Three-Primary Win

Mitt Romney went on the attack Wednesday against U.S. President Barack Obama, a day after taking command of the race to be the Republican contender in November elections with a triple primary win.

In a speech to newspaper editors here, Romney blamed Obama for failing to turn around the U.S. economy quickly enough and took a page from his own critics by accusing the president of hiding his true intentions from voters.

Romney said he was troubled by the president's recent remarks on an open microphone to Russian President Dmitry Medvedev asking for "flexibility" until after the U.S. elections.

"What exactly does President Obama intend to do differently once he is no longer accountable to the voters? Why does flexibility with foreign leaders require less accountability to the American people? And on what other issues will he state his true position only after the election is over?" he said.

Romney's broadside came a day after Obama used the same forum to call the former Massachusetts governor to account for supporting a "radical" budget passed by congressional conservatives last week and accusing him of "social Darwinism."

With the thrust and parry, the presidential campaign appears to have entered a new phase, one in which Romney seems to have finally shaken loose from the Republican pack to focus on Obama and the November 6 elections.

His main rival for the Republican nomination, Rick Santorum, did not even rate a mention in Romney's speech, the morning after the former Pennsylvania senator went down to defeat in primaries in Wisconsin, Maryland and the District of Columbia.

"We won them all! This really has been quite a night," Romney told supporters in Wisconsin, where he won by nearly five percentage points.

Santorum vowed to fight on, traveling to his home state of Pennsylvania to campaign for the next Republican primary later this month.

"The clock starts tonight," Santorum told supporters in his home state of Pennsylvania, which votes later among a slew of other East Coast states on April 24.

"We've got three weeks to go out here in Pennsylvania and win this state. And after winning this state, the field looks a little different in May," he said, referring to upcoming votes in more conservative states such as Texas.

But with delegates piling up in Romney's column, the electoral math told a different story, one of rapidly diminishing prospects for a Santorum candidacy despite strong support from religious conservatives.

Romney has 652 delegates after Tuesday's primaries, well over half the 1,144 needed to be crowned the Republican flag-bearer at the party's national convention in Tampa, Florida in August.

He is already acting like the nominee, training his political fire on Obama's "government-centered society" and no longer mentioning his Republican rivals on the campaign trail.

Romney must still overcome skepticism from conservatives, who fear the ex-governor of liberal Massachusetts will tack to the left once he wins the nomination in order to appeal to the all-important independents.

"He now is halfway to the nomination, but only halfway," said Steffen Schmidt, a political scientist at Iowa State University. "He is the inevitable nominee, still tortured by the other three contenders in the GOP."

"There are still too many 'Anybody but Romney' Republicans so it will be a big effort to bring them on board," he said.

Santorum, a Christian conservative and staunch opponent of abortion and gay marriage, virtually ignored Tuesday's contests in Maryland and the District of Columbia, to concentrate on the important midwestern state of Wisconsin.

But with nearly 100 percent of precincts reporting, Romney had 43 percent of the vote to Santorum's 38 percent.

Romney won 49 percent to Santorum's 29 percent in Maryland and dominated with 70 percent in Washington, DC, with former House speaker Newt Gingrich and Texas congressman Ron Paul trailing far behind in all three contests.

"Let's face it. Mitt Romney is going to be the nominee," said prominent Romney supporter Tim Pawlenty, a former Minnesota governor.

Romney has now won 24 out of 37 contests and amassed some 625 delegates of the 1,144 needed, according to a tally by website RealClearPolitics.

Santorum has racked up 11 victories and has well under half Romney's delegate count.
