The Unlikely Swing State: Romney can win without Wisconsin, but if he does win it, he probably wins the election
Christian Schneider writes on NRO: When Wisconsin residents awoke on the morning of November 5, 2008, the news that Barack Obama had won the state by 14 percentage points had to be a bit of a shock. In the two previous presidential elections, Wisconsin had been the "swingiest" of the blue states.
Since 2008, the state has swung strongly to the right at the ballot box. In 2010, both houses of the state legislature lurched from Democratic to Republican control, GOP governor Scott Walker was elected, and Republican businessman Ron Johnson defeated the 18-year incumbent and liberal stalwart, Russ Feingold, for a seat in the U.S. Senate.
