Mitt Romney has had issues in this campaign with cars.

You may remember his "two Cadillacs" comment in February, immediately characterized as a gaffe for a candidate who has often seemed to struggle with how to address his wealth on the trail.

"I like the fact that most of the cars I see are Detroit-made automobiles," said Romney in Michigan. "I drive a Mustang and a Chevy pickup truck. Ann [his wife] drives a couple of Cadillacs, actually."

The GOP candidates for president have seized on high gas prices as a line of attack against President Obama, largely saying the answer is more domestic oil drilling.

But GOP front-runner Mitt Romney used to have a position seemingly at odds — at least in emphasis — with what he and the other Republicans are now advocating.

As Massachusetts governor, Romney said high gasoline prices "are probably here to stay," and he advocated policies to cut energy demand.

The U.S. House of Representatives is scheduled to vote Thursday on what's known as the Ryan budget, the spending plan from Budget Committee Chairman Paul Ryan, R-Wis., that among other things changes the structure of Medicare and rewrites the tax code. Presidential candidate Mitt Romney has endorsed the plan, but some are saying his rhetoric on the campaign trail may not match up with at least one reality of the Ryan budget.

Romney said he supported the Ryan budget the day it was unveiled.

"I applaud it," he said. "It's an excellent piece of work, and very much needed."

The Senate passed a bill Thursday to explicitly ban insider trading by members of Congress and the executive branch, and that means the Stop Trading on Congressional Knowledge Act is headed to the president's desk.

But this STOCK Act is quite a bit weaker than earlier versions.

The STOCK Act has been on a glide path ever since an explosive 60 Minutes story last fall highlighted the issue of members of Congress apparently profiting on nonpublic information.

Wisconsin Republican Rep. Paul Ryan releases the House GOP budget Tuesday, likely including a proposal to restructure Medicare. That idea brought much criticism from Democrats and advocates for the elderly when Ryan pushed it least year.

Mitt Romney won the GOP presidential primary in Ohio Tuesday night. Unlike most of the other states voting on Super Tuesday, Ohio will be a pivotal swing state in the general election.

Now, to Super Tuesday. Ohio may not offer the most delegates of the ten states who will vote on Super Tuesday, but it has become the most coveted state for all the candidates of the Republican nomination for president, a microcosm of the countrywide fight for supremacy. Newt Gingrich, Rick Santorum and Mitt Romney will all campaign there today. NPR's Tamara Keith has this campaign update from Cleveland.

Rick Santorum is trying to shake up the Republican primary by winning the primary Tuesday in Michigan — and many polls show him neck and neck with Mitt Romney. He's a former senator from Pennsylvania best known as a culture warrior. What's less well known is what he did after losing his re-election bid in 2006.
