Here’s the new ad from McCain/Palin:

As Ed notes, it’s pretty effective: it tries to talk to the viewer and is notably more optimistic than whatever his opponents are throwing at the wall today (mind you, it’d be hard for us to keep a straight face if Obama/…Biden, right… tried optimism, given that their entire campaign is based around how the universe will implode unless you give him five bucks). It should be interesting to see which approach works better. I’m trying to remember the last time that optimism didn’t, but no doubt that’s in the eye of the beholder.
