That really is a mystery. I don't know much about Nevada, but their regular reelection of this creature makes me question the whole state's sanity.
People like Rahm Emanuel, the Klintonx, Durbin the Turban, Barack Obama, DiFi and Babs, and that clutch of inveterately Pink Northeastern senators who like to lay back and let others advance the talking points: Harris Wofford, Charlie Schumer, the late Teddy Kennedy, Chris Dodd, Paul Sarbanes, Barbara Mikulski.
Guys like that.
