One of the most effective ways I've used to convince fairly rational fiscally conservative people to hate Republicans is by reciting how much they've spent on a stupid Republican boondoggle.
"You've spent $1,500 this year to bomb Afghans. Did you know that? Oh wait. I forgot, you make twice the median income. Make that $3,000 to bomb Afghans."
(Of course, now I'd have to say, "they just took out a $5,000 dollar loan in your name with which to bomb Iraqi civilians.")
Works like a charm, with the added advantage that people believe dollars are a more real sign than other facts. They think of all the added features they could have had on their last car with that $5,000 and it feels "real" to them.
So why aren't we asking people, "Say, did you hear the Republicans just put an accused money-launderer in charge of your pocket-book?"
