Republican long shot Rick Santorum poked holes in Mitt Romney's aura of inevitability Tuesday night with a trio of upset victories that shifted the dynamic of the 2012 presidential contest.
The former Pennsylvania senator's wins in the Minnesota and Colorado caucuses and Missouri primary were setbacks for Romney, the national front-runner, who had been expected to cruise easily through a series of relatively minor February voter tests. He must now wait three weeks to regroup, when Arizona and Michigan hold what suddenly are shaping up as unexpectedly important primaries.
In remarks to delirious supporters in St. Charles, Mo., Santorum took a swipe at Romney's big advantage in money and the negative ads he's used to defeat his opponents in previous states. He also lashed out at President Obama, describing him as someone "who thinks he knows better" and doesn't listen to the American people.
"Ladies and gentlemen, I don't stand here to claim to be the conservative alternative to Mitt Romney. I stand here to be the conservative alternative to Barack Obama," Santorum said, setting off chants of "We pick Rick!"
Reflecting what he sees as the altered shape of the race, Santorum told CNN that "now we're in a little bit of a no-man's land" as the candidates move into states where they haven't had months, or years, to campaign.
Romney, who won Minnesota four years ago, was running a weak third behind Santorum and Ron Paul.
Speaking to a deflated crowd of backers in Denver, Romney said he was "pretty confident" he would come in either first or second in Colorado's caucuses, his last hope for salvaging a bad night. But hours later, state Republican Chairman Ryan Call announced over CNN that Santorum had won.
He congratulated Santorum and said that he looked forward to coming contests and a united party when the primaries ended. But he also struck a pose as a populist outsider, speaking of his father's humble roots and casting himself as the antidote to the problems in the nation's capital.
