I find the conniptions that many on the Republican right seem to be having over John McCain being the likely Republican nominee for the Presidency of the United States quite revealing. The president is supposed to be the person that the buck stops with. I would expect the person so charged to be able to understand policy but not that they be the fount of all knowledge when it comes to policy. Instead the Limbaugh's of the world want to know what the nominee thinks about each and every issue in advance and is he/she sound on that issue. Rather than consider the concept that the right choice might be the person who can make a judgment call on a issue that is yet to arise. So McCain failure to be onside regarding immigration has made him a villain to the right.
As Sorkin said via Michael Douglas "I've been here three years and three days, and I can tell you without hesitation: Being President of this country is entirely about character."
I would also suggest that if someone from Huckabee's team were to suggest in a manner that gets the message out there without being too defeatist that the race for them is now about who would be the best conservative VeeP to keep McCain in line then he might be able to swing some southern states that appear to be out of reach for him at the moment with the conservative vote too split between Romney and Huckabee. It is entirely possible that if McCain runs away with the primaries that he will do his own thing with regard to VeeP. Remember he is 71 and he will know that the VeeP have to be someone that can do the job as McCain would do it. He could even decide to step outside the usual Senator/Governor from a swing state. That might involve plucking a congressman or even a figure outside current mainstream elected politics. Say Christine Whitman, who would put New Jersey in play.
