We've heard all of the "it doesn't matter if a person is pro-life or not" crap before.
An innocent American is murdered EVERY 24 SECONDS in the United States. If that isn't relevant I don't know what is.
It’s not relevant to the position he’ll be taking. He can make no change whatsoever to abortion law as vice-president unless there’s a 50-50 tie. Ryan is clearly pro-life and can be judged on his record in congress. Romney and his advisers are trying to get everybody on the same policy page (which is totally stupid but whatever).
