Mike Huckabee got the Iowa Republicans to vote for him. He's a lot more electable, for a number of reasons. One problem is that his politics, except where they involve pro-life issues, are indistinguishable from a left-wing Democrat's.(See Mike Huckabee And Hispanics Vs. America, August 17, 2007)
Ron Paul was fifth in the Republican Caucus, which is to say, just about where McCain was, within limits of error. Look for the media to keep on saying how viable and Presidential McCain is, (the media themselves are actually McCain's base) and look for them to not say anything like that about Ron Paul.
