Exactly. Example: How the hell does labor vote for environmentalists who kill union jobs?
Also, How do Christian blacks vote for homosexual marriage, adoption, etc.? How do Jews vote for an annihilationist policy towards Israel? How does the free-speech crowd vote for hate crimes? How does a Yellow-Dog Democrat vote for appeasement? And on and on... the Dems have gotten away with this stuff for a long time, but the reality of the post-Clinton, post-9/11 world has almost completely stripped the pretty facade that the Democrats had put up to distract from these contradictions. The louder the activists shout, the more the aforementioned voting blocs have to wonder about a party so passionate about positions they abhor.
