Forgive me for being confused. What is the truth? Did the left really love him in the past? Or did they only ever want McCain in the past because they knew he was the weakest candidate (in terms of base Republican support), and therefore easiest to beat?
I'm left but independent, vote by candidate and issue, not party. I didn't vote in '92 (my first eligible year) for various reasons but would've voted for Clinton. Voted Dole in '96. Gore in '00, Kerry in '04. Will vote Obama in '08. If McCain had been the GOP nom in '00 I would've easily voted for him rather than Gore.
The "truth", for lefties who honestly did like McCain in '00, is that McCain has changed
massively in the last eight years. He has been a Bush supporter, Bush shill, and has destroyed (to some lefties' perspectives) the qualities that made us really respect him. The independence, the careful consideration of issues and voting for or against them only from that instead of party line. The moderate political leaning.
The biggest thing that made me lose respect for him was his willingness to get on the stage at the '04 RNC and speak for a George Bush second term. Similarly the biggest thing that made me lose respect for Colin Powell was his presentation before the UN leading to the Iraq invasion. He did gain back a bit by later quitting though.
McCain isn't the only one to suffer from his enabling of Bush. I still refer to the Patriot Act and the "use of force" bill to see which Congresspeople sold our future for momentary emotions and horrible intelligence, and which stood by the principles of this country and the power of reason. Bush's policies dirtied a lot of politicians I'd formerly respected. I'll never vote again for my state's two democratic senators for example (Boxer and Feinstein) due to their votes.
Last year, even with this loss of respect, I still viewed him favorably. My favorites last year were Kucinich, Clinton, and him. I didn't know much about Obama. Kucinich obviously went out early, and I liked more about Obama as I saw him, and less about Hillary. McCain was about as I expected. But this last month has again made me lose respect and support. He picked Palin, imo a typical idealistic right extremist. He allowed for dirty ads to go on TV. He made the crazy move to suspend his campaign and try to take credit for the bailout, then withdrew when his bluff was called.
So yeah, there are real policy and character reasons why my support for him has waned considerably in the last eight years. If he's elected I really, really hope he'll return to his old ways. If he continues this vector of support for Bush's policies, or if he lets Palin's rightist philosophy influence him, it'll be a terrible end to a formerly grand career.
