Hmmm. In a Gallup/USA Today poll taken over the weekend, Paul Ryan's net favorability is -3%. As Dave Weigel points out, even Sarah Palin, who had a famously rocky rollout, had a net favorability of +15% or so by the end of August. This is supposedly due primarily to the fact that Ryan isn't well known, but I'm not so sure about that. Among non-political junkies (i.e., normal people) Jack Kemp wasn't very well known. Cheney wasn't well known. Biden wasn't very well known. And Palin wasn't well known. But initially, they all polled better than Ryan.
