I'll try, but this is a family forum, so I may not be able to.
I would vote for Hillary! before I vote for John McCain. I dislike Hillary! more than just about any other human being, but if it came down to her and McCain, I would volunteer for her campaign, drive Democrats to the polls, and stuff envelopes for the Donks form sun-up to sun-down.
Be careful. I've said pretty close to the same thing in past and it's caused heart palpitations among some. ;-)
I certainly guarentee if enough foolishly selected him, that I'd spend every waking day and night talking to my friends/collegues who ARE either largely "Independent" or on the more conservative/moderate scale of the Democratic Party. You know, the people McCain thinks he can substitute in place of conservatives he lacks. I'll spend my time advocating against McCain to them, whereas last election I spent my time pulling FOR Bush.
McCain's going to have his own "AnyBody BUT" movement, only it's going to be a two pronged attack. From Democrats that support the Dem nominee, and from conservatives that have too much sense not to recognize the damage Mccain could do within the W.H. To this country AND the party/conservative movement.
Then you are a fool.
