mccain lieberman would be interesting,i dunno the "conservatives" are referring to mccain as to liberal as it is,so they would lose votes there,but they would surly gain independent and democratic votes.. i dont see that happening either though..
Whoever the GOP picks it will be a paleoconservative in the vein of Bush or Huckabee. I really doubt he'd pick someone like Liberman.
If McCain picks Jeb Bush, then it would further prove how stupid he really is, because nobody with half a brain is going to vote for another Bush. Then again, I am sure these guys don't pick anything themselves. They are puppets and their picking is done for them... kind of like an arranged marriage. It's all very irrelevant to me. They could put Humpty Dumpty in office and it wouldn't matter. If I had to make a guess about McCain's running mate, just for the fun of it, I would say it will be Mitt Romney, and there is a lot of evidence suggesting this might be the case.
And what makes Bush or Huckabee "paleoconservatives"? Most people don't even know what conservatism is. These people are all big government socialists who hide under the guise of religion and family values to dupe their target demographics. It doesn't make them conservative. 99.9% of the Republican party are neoconservatives, and neoconservatism is rooted in Trotskyism. It has nothing to do with traditional libertarian conservatism, which is virtually non-existent, with the exception of perhaps Ron Paul.
