A Democratic source responds to reports that Rep. Paul Ryan (R-WI) is Mitt Romney's VP pick:
Romney picking Paul Ryan is a sign that he has no balls. The push to add Paul Ryan to the ticket is a recognition that the GOP isn’t enthusiastic about Romney. Ryan’s an ideologue who has championed an extreme agenda that alienates a lot of swing voters and key voting blocs like seniors. If Romney picks him, it will be a clear capitulation to the right wing of the Republican Party. And we know it’s a concern to House/Senate GOP candidates to have him on the ticket, because it will elevate the Ryan budget, so Romney picking him would be a signal that he’s willing to throw those concerns aside to please GOP insiders/right-wingers.
