The selection of Wisconsin Rep. Paul Ryan as Mitt Romney's running mate is sure to excite the Left almost as much as it does the Right.
Ryan, 42, has been considered a rising star in the party for years. He's been the chairman of the House Budget Committee since Republicans took back control of the House in 2010, and he's known for his keen fiscal knowledge. Plus, he hails from an important state. The GOP has been hoping to take Wisconsin this cycle. Although the state hasn't gone red in a presidential race since 1984, Republicans have been buoyed by the successful gubernatorial race of Scott Walker, who became the first governor to face a recall election and win last June.
