Republican Mitt Romney campaigned this weekend in a state that has not seen much of either presidential candidate. Nobody considers Indiana a toss-up in the presidential race.

But the Senate contest there is a different story. It's a very close race, and the result could determine which party controls the Senate next year. So Romney showed up at a barbecue shack in Evansville to give the conservative Republican candidate a boost.

'Help Me Elect This Guy'

While President Obama and Gov. Romney battle for the hearts and minds of the middle class this election season, there's a huge swath of Americans that are largely ignored. It's the poor, and their ranks are growing.

Swimming the final race of his Olympic career, Michael Phelps gilded his resume just a bit more, helping the U.S. men's 4x100m medley relay team claim the gold medal at London's aquatic center. Phelps turned away a surprising challenge from the Japanese team, which had the lead when he went into the water to swim butterfly, the relay's third leg.

It was the 18th gold medal of Phelps' record-setting Olympic career. He leaves the London 2012 Games with 22 Olympic medals overall.

Swimming in London's Aquatic Center, the U.S. women's 4x100m medley relay team set a new world record in winning a gold medal, with Allison Schmitt swimming freestyle to anchor a relay that finished two seconds ahead of the competition, at 3:52.05.

All four members of the women's relay team had previously won gold in their events: Dana Vollmer (butterfly), Missy Franklin (backstroke), Rebecca Soni (breaststroke), and Schmitt.

The victory gave Franklin, 17, four gold medals and one bronze in the London 2012 Games.
