I don't believe Ryan would have been picked if Wisconsin didn't look competitive.
If the candidate thinks certain state look competitive, it doesn't mean it's really competitive.
McCain tried to make Pennsylvania competitive in 2008, as vital part of his strategy, and failed miserably. There are other states Romney should be focusing on rather than Wisconsin.
Look, I can understand Romney is hoping to appeal to a certain group of voters, but from geographical point, Ryan selection hardly gives him much.
