The Club for Growth has a chart of every member of Congress's record on 19 Jeff Flake anti-pork votes.
My representative is the Queen of the Democrats, Nancy Pelosi. She voted in favor of pork all 19 out of 19 times. Why would a partisan like Pelosi support Republican pork so consistently? Simple. If there's one principle she holds above partisanship, it's "You scratch my back, I'll scratch yours." She supports their pork and they'll support hers.
How did your Congressman do?
