With less than 24 hours until the polls open in the pivotal Michigan primary, the Democratic National Committee (DNC) is again hammering Mitt Romney for his stance on the auto bailout.

Lawmakers in both chambers will try to revive their push to pass new transportation bills, although the House is unlikely to consider a new version of the Republican highway bill.

Republican presidential candidate Rick Santorum said Saturday that the GOP would be unable to contest the issue of government bailouts if they nominate former Massachusetts Gov. Mitt Romney to challenge President Obama's bid for re-election.

Speaking at the conservative group Americans For Prosperity's forum in Troy, Mich., Santorum again criticized Romney for his positions on bailouts from the federal government to Wall Street companies and the U.S. auto industry.

Santorum said Romney supported bailouts for the financial sector, but not General Motors and Chrysler.

"I wasn't for bailouts...capitalism works," he said. "It takes time, but you've got to believe in it...What I don't understand is how some people would bailout Wall Street, but not Detroit."
