Is he using it as an allegory for his future campaign or Christian conservative movement? The problem is that Huckabee has overstayed his welcome and he’s not making any friends for 2012 or 2016. The party establishment is trying to push him out of the race but he isn’t listening. I think it demonstrates his stubbornness which can be good or bad but if he’s this obstinate despite the odds, it doesn’t bode well for his ability to lead.
He should listen to the voters because they are telling him they aren’t interested in his campaign, he almost lost in Washington to a guy who wasn’t even in the race.
Though, here’s a case for why it’s good for McCain that Huckabee’s still in the race.

But with a nominal GOP race still going on, McCain has a rationale for claiming victory after each new contest and, wanting to be fair and balanced, the media must give him his due.
And McCain is taking advantage of it with the sort of lines that are ripe for TV and radio replay. Last week, it was his closing promise that he, too, is “fired up and ready to go.”
Last night, McCain cranked up the anti-Obama rhetoric, saying his likely general election rival’s rhetoric amounted to an “eloquent but empty call for change.”
Naturally, Obama’s thrashing of Hillary Clinton dominated the headlines and first paragraphs of all the stories today. But high up and before the jump in the Washington Post, New York Times and Wall Street Journal was McCain’s “eloquent but empty” quote.
