Do you think this is a better candidate than Palin?
Yes. He basically has more experience than Obama had, and a greater leadership role in the House. Considered to have "gravitas." Younger. Holds the right while Romney tries for the center.
Will bring the focus on the economy.
Probably does help out in WI, IA and OH. May help out in the South (VA, NC).
Problems are with seniors and Hispanics. Problems with FL, CO, NV, NM, even AZ. Little help in the Northeast.
A potentially good choice, but not a great one.
I think Ryan could help out in NH. Granite Staters are an odd bunch and worry a bit more about deficits than is typical. Whatever one may think of Ryan's proposal of how to get there, he certainly is the most serious of the short-listers when it comes to tackling the deficit.
I doubt he helps enough in Wisconsin to deliver the state in a close national election. Nuevo Mexico was never in play no matter who was picked.
