Six-term Republican Sen. Richard Lugar of Indiana is facing his first primary challenge since winning the job in the 1970s. The race is attracting big money from outside groups and superPACs, and is seen as a test of the strength of the Tea Party movement versus the power of incumbency.

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.

This morning, House Republicans unveiled a new budget plan on Capitol Hill. And like President Obama's budget document last month, the GOP's version is as much a political statement as an actual road map. NPR's Tamara Keith has that story.

TAMARA KEITH, BYLINE: In some ways, this budget is a sequel. This time last year, House Budget Committee Chairman Paul Ryan unveiled a controversial budget document that passed the House with strong GOP support.

Perhaps it's fitting that the state that kept everyone up late last night, waiting for results, was Ohio. It's a swing state, and it seems every four years, in the fall, Ohio becomes the center of attention in a presidential election.

This year, as NPR's Tamara Keith reports, it just happened a little earlier.

TAMARA KEITH, BYLINE: Talk to Ohio voters - Republicans and Democrats alike - and there's one issue that rises above all the others.

MARVIN HAYWOOD: Number one: our economy.

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.

The battle over social issues in the Republican presidential primaries has extended through most of another week. This time the flashpoint was a remark by Mitt Romney. The former Massachusetts governor said he opposed, and then clarified that he actually favors, legislation involving contraception.

NPR's Tamara Keith reports it was not what Romney intended to discuss in Ohio.

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.

It goes without saying that the men who are vying for the Republican presidential nomination found serious flaws with the budget plan President Obama released Monday. But it got us thinking that this might also be a good time to dig into the budget plans offered by the GOP candidates.

All of the candidates want to cut government spending and balance the federal budget. They also want to cut taxes.

When President Obama unveils his budget Monday, it will project a $1.3 trillion deficit this year, and just under $1 trillion in 2013. It would increase spending on education, research and development and transportation. It would also increase taxes on the wealthy and cut spending, including on defense.

Presidential budgets are almost always aspirational documents. They lay out a vision, not what the president actually thinks will happen.

The House on Thursday passed a bill that would ban congressional insider trading. The STOCK Act passed overwhelmingly, 417-2, despite some partisan disagreements over its scope.

With congressional approval at all-time lows, the bill was widely seen by lawmakers as a small step in restoring public confidence. But differences remain to be worked out with a Senate measure, passed last week, before a bill could be sent to President Obama.
