As Mitt Romney’s running mate, Paul Ryan is a national political star. But the veep campaign isn’t his only race. Back home in Wisconsin, he’s seeking reelection to the House. In his final congressional ad of the year, Ryan and his wife, Janna, talk about the “idea of America” as their children play on a swing set. The ad, which will air on Milwaukee and Madison TV stations, will likely help the Romney campaign as it makes a play for the Badger State’s ten electoral votes.
