Iowa's curmudgeonly senior senator, Chuck Grassley, is easily the funniest senator on Twitter. And in this new "youth-targeted" reelection ad, the old grump promises to tweet more often, for the people, until he finally keels over.

But no, "Chuck Grassley has a Twitter" doesn't mean anything bad ladies! It's just a platform for Grassley to disseminate his special flavor of nonsense, such as this classic from last summer:
