Of the 10 “Yes” voters you note, I see at least 3 of what might be referred to as gravy-train Republicans.
Doesn’t surprise me a bit that they’d be on the wrong side. They know how to get rich.
That's kind of where I'd put Thune. He'll get 90% conservative ratings on scorecards because he votes the "right" way on foriegn policy, social issues, and tax cuts, but when it comes to pork and spending, he's a big-government conservative and loves his pork so much that he's willing to toss any conservative to the wolves who gets in the way of his latest pork project.
Better than an America-hating Democrat, but not the kind of person you'd want to promote for higher office.
Bilbray's turned out to very good considered his past as a RINO though.
