How does the GOP respond? Well, lie, for one thing. The Romney/Republican lies about Medicare, which Ryan would end as a single-payer insurance program, are a start.
Another good way to paper over Paul Ryan is to attack the Democratic vice president Joe Biden. He does stick his foot in his mouth now and again, so the soundbite game is easy to play..
I think that's at least part of what's at work in a popular Republican talking point this week.
Type the words "Obama to drop Biden" into Google and you'll get a flood of links. Again and again, they are links to speculative stories from the likes of Fox, Weekly Standard, Daily Caller and other right-wing organs and blogs. The rare links to mainstream media are to articles quoting experts like Sarah Palin on the advisability of dropping Biden from the ticket. Got it. Message; "Our guy is better than your guy. And Hillary Clinton is better than all of them, but your presidential nominee is a black Muslim from Kenya, too stupid to give her a rightful place at the top of the ticket."
Cagey attack ploy. Careful what you wish for, though.
