The purpose of propaganda is not to get people to believe in lies; the purpose of propaganda is to murder the idea of truth.
Mission accomplished. The general public now understands that one cannot believe a single thing that is said by any candidate ever, at any time. This has been accomplished not just by a series of broken political promises—that more or less goes with the territory. But the news media and journalistic establishment have connived in the reduction of politics to pure propaganda, calling some politicians liars for having said things that they never said (e.g. Al Gore inventing the Internet), and letting flagrant lies from other politicians pass without comment, save for the "others disagree" squib in the next to last paragraph of the article.
That leaves us with the idea that "character" and "image" are the only important factors to use in evaluating candidates. So let's have at it.
Huckabee is running as a fundamentalist preacher. That seems to be working. Giuliani is running as the biggest bastard on the block. That seems to sell pretty well also.
Romney is having trouble because he can't convince the Republican base that he's not a Mormon. That is the only thing that will work for him, BTW; convincing the base that the LDS aren't a satanic cult is simply impossible. Thompson has lost the "I play one on television" mojo, so now he's just an old guy with a hot wife, and Kucinich might win the Republican nomination (despite his being a Democrat and all) if that were the standard. It just depends on whether you like blonds or redheads, although Kucinich's wife is a Brit and her accent would make most Republicans think that she's too smart to be First Lady.
You'd think that having been tortured would give McCain a leg up, but only losers get tortured, so he's out. Ron Paul is genuine, if by "genuine" you mean "self taught wacko," (again, very appealing to certain elements).
Over on the Dem side, Kucinich has as much chance of winning as he does as a Republican. Biden has a lock on the "Hair Club for Men," vote, but the only way he could finish farther out of the money would be to die his hair plugs green. Richardson is running for Vice-President; everyone knows it and everyone thinks he's doing a great job at it.
Dodd seems to be trying for the Integrity, Courage, and Constitutional Values vote, which means that he won't carry a single state. And there's certainly no money in it.
Among the front runners, you have a black man who isn't considered black, a woman who's supposed to be a lesbian martian cyborg, and a rich white guy who is the champion of the poor. None of the three is crazy, which is a distinct plus. Also, all three benefit from the idea that you shouldn't believe what they say, since that would interfere with their being all things to all people.
It's not clear what will happen when the electorate realizes that Oprah isn't married to Obama, and that Hillary is, in fact, a woman. I'll just repeat my frequent warning: never rule out the middle-aged white guy.
