People don’t vote for vice presidents.
More often than not, it's good for picking up the VP candidate's home state. Also, although he wouldn't necessarily be my choice, Huckabee on McCain's ticket would likely pick up a lot of evangelical Christians who otherwise wouldn't vote for McCain.
Correct, however you are ignoring the political reality that VP candidates are there to create an attraction to the overall ticket, i.e. the balancing concept of North/South, Senator/Governor, etc. In this case, my position is there is no VP possibility that can bring any balance to my aversion to McCain as the presidential candidate.
Choosing for the lesser of two evils may not be palatable, but it is often wise.
While it may be wise in your worldview, it remains evil in mine...just sayin'. While I don't make this choice lightly or with any notion that I am a better person than anybody else that makes other choices, I do understand that the world, or at least the US, is likely to be a very different place on 1/20/09 and I shall have been a part of how it got there, for good or ill. I have carefully considered this matter and know that for all the consequences I can envision for this choice, there are multitudes of consequences that never even came to my mind and I shall also have to live with those.
