On that count, I wouldn't be surprised. This guy is so thoroughly unvetted, he's going to make Palin's private life look like Mitt Romney's.
Ryan hasn't run for statewide office before, but he's been in the national spotlight for years. His name recognition among the public is low, but the political press know who he is. Also, I'm confident that the Romney campaign has thoroughly investigated his personal life; this pick doesn't compare to the panicked and unplanned manner in which McCain chose Palin.
