All I have heard about since the other night is the Eastwood speech, how it is supposedly an embarrassment for the campaign, blah blah blah. You know what it means? They've got nothing. If that's the only angle they can attack from, then they're in total desperation mode.
I didn't hear the entire Eastwood bit, but what I did hear was pretty clever IMO. Sure he stammered at times, but how many older people don't? The cleverness of the bit indicates he's certainly not having any mental problems. Plus he's still Dirty Harry, which means he's still infinitely more badass than Mr. Mom-Jeans.
They've got nothing. They can't run on anything, and their attacks against Romney and Ryan just aren't sticking. All they've got left is the Flying Monkey brigade, crapping in their hands and slinging it at anything in the general vicinity. Headline after headline on Google News about Eastwood's speech proves it.
