There's an old shorthand for likeability in politics: "Which candidate would you rather have a beer with?"

Republican presidential nominee Mitt Romney's proposal to overhaul the tax code continues to draw scrutiny.

Romney says it is possible to cut tax rates without driving the government deeper into the red, and that he can make up for the lost revenue by closing tax loopholes. But analysts have had a hard time testing Romney's claim because he hasn't offered many specifics.

When he was pressed by NBC's David Gregory this weekend to give an example of a loophole he would close, Romney didn't offer much detail.

This is ALL THINGS CONSIDERED from NPR News. I'm Robert Siegel.

Four years ago, then-Senator Barack Obama took the stage in Denver to accept his party's presidential nomination. He spoke of overcoming partisanship and economic turmoil. Well, tonight, President Obama will do it again with four years of experience under his belt. Since taking office, he has struggled to overcome a crushing recession, a weak recovery and a deeply divided electorate.

NPR's Scott Horsley has this story on the path the president has traveled.

President Obama holds a Labor Day campaign rally in Toledo, Ohio, on Monday, and then flies to Louisiana to inspect the damage from Hurricane Isaac. The Toledo rally is part of a long weekend of campaigning, leading up to the Democratic National Convention, which starts Tuesday in Charlotte, N.C.

The president held a rally with thousands of students at the University of Colorado over the weekend. Just five days earlier, he'd been at Colorado State. Obama is hoping to harness the cross-state rivalry between the schools in the service of his re-election campaign.

On Friday, President Obama was at Fort Bliss, Texas, where he spoke to troops and met with military families, including some who lost loved ones in Afghanistan.

As that war winds down, the president is ordering additional help for those with invisible battle scars. A rash of suicides has shown mental injuries can be just as deadly as a roadside bomb.

Surrounded by soldiers in camouflage fatigues, Obama recalled his last visit to Fort Bliss, exactly two years earlier. That was the day he announced a formal end to combat operations in Iraq.

After weeks of saying he would not release his tax returns, GOP presidential candidate Mitt Romney told reporters Thursday he had checked them and could report he had always paid at least 13 percent annual in federal income tax. But Romney still refuses to make public more of his tax returns, despite a new offer from the Obama campaign.

The stock market rallied on Friday's jobs report, with the Dow Jones industrial average jumping more than 200 points. But what do the numbers mean for the political stocks of President Obama and his Republican challenger, Mitt Romney? That's harder to measure.

In the days since the movie theater shooting in Aurora, Colo., there's been little discussion of the laws that allowed the gunman to acquire his arsenal.

Authorities say suspect James Holmes, who was arrested at the scene of the shooting that killed 12 people and wounded dozens more, was armed with a modified assault rifle, two pistols, a shotgun and thousands of rounds of ammunition.

Colorado Gov. John Hickenlooper, a Democrat, told CNN this weekend that the guns are not the problem.

President Obama's campaign continues to hammer presumptive Republican nominee Mitt Romney over the GOP challenger's refusal to release more of his tax returns. Romney has provided one year's record and promised a second year's worth of returns. But even some of his fellow Republicans now say that's not enough.
