Arlen's more of a fighter than Hatch, I think. Too bad he's not reliably on our side.
Hatch has a longer fuse, but we went after Schumer two years ago for asking Roberts what Hatch characterized as "Dumb Ass" questions. He's not a bully, but Hatch has a backbone and he's far more reliable then Specter. I hold my breath with Specter.
