President Obama is leading presumed GOP nominee Mitt Romney big in recent national polls.

No, wait. Polls show he's trailing Romney by a couple of percentage points.

Oh — this just in: Obama is actually leading Romney, but the race is tightening.

It's a general election poll-a-palooza out there, people.

But what do all the numbers mean?

"I have friends who support Obama, and friends who support Mitt Romney," says Scott Keeter, survey research director at Pew Research Center. "I tell them not to get too excited or too depressed at this point."

Medicare patients who reach the annual gap in coverage for prescription drugs known as the "doughnut hole" are 57 percent more likely than those with continuous insurance coverage to stop taking drugs for heart-related conditions such as high blood pressure or heart disease.

For most mothers, there is no event in life bigger than giving birth to a child. Charity Lovas has given birth to eight children, yet only three of those children are her own.

It all began in 2002, when she and her family were living in Indianapolis. She says she was reading the Sunday newspaper and spotted an ad for ovum donors. She had never heard about it. She was curious.

She called the number in the ad. A woman at the other end of the line explained the egg donor program, and said they had a surrogate program, too.

For years, the U.S. Department of Justice has known that flawed forensic work by FBI experts may have led to the convictions of innocent people, but prosecutors rarely told defendants or their attorneys, according to an investigative report in The Washington Post.

The must-read story of the day if you're into practical jokes has to be The Wall Street Journal's piece headlined "Walk The Prank: Secret Story Of Mysterious Portrait At Pentagon."

As Melissa Block and Audie Cornish will explain later on All Things Considered, last year some pranksters hung a portrait on a hall in the Pentagon with a plaque saying it was "Ensign Chuck Hord. USNA circa 1898. Lost at sea 1908."

There is no such person.

Chrysler, Ford and General Motors gained market share in the past couple years. Helped by Toyota's much-publicized recalls, the problems that Japanese carmakers faced after last year's earthquake and tsunami, and an improving reputation for the quality of American-made vehicles, Detroit's Big Three grabbed 47 percent of sales last year — up from 45.1 percent in 2010 and 44 percent in 2009.

Our friend Micki Maynard of Changing Gears, though, reports that the Detroit companies' comeback — in terms of market share — may be over.
