I know that wasn't directed to me, but here's my 2 cents. I wouldn't vote for McCain under any circumstances because I will not vote for Democrats under any circumstances. I was at the county convention in my state. His supporters were the most vile Dems I have ever been in the same room with.
And come election time, it is people like myself and a few others who have and will take advantage of that mindset. When you have a voter who is indecisive or less than thrilled about his party's nomination there are ways to create an atmosphere of disgust or repulsion to the candidate and cause the voter to 'sit home.' Kerry was perfect fodder for this!
