Grassley on Knucklehead List
Salon lists 12 Senate "knuckleheads." Woowoowoowoowoo. Not listed: Congressional nitwits, morons and nincompoops.
"Evidence of knuckleheadedness: Oh, pretty much just the entire debate over healthcare reform. Grassley's the primary Republican negotiator on healthcare in the Senate, and Democrats have been working hard to please him, but at this point no one besides Sen. Max Baucus, D-Mont., understands why.
And don't even get us started on his use of Twitter."
It's a mostly GOP list, but Baucus and one other Democrat qualify.
