Here's the fear we Dems have. I'm not arguing with your position that the Republican Party is not inherently a problem, because you're absolutely right - it's not. Some of my best friends are, and all that. So, it's not a Republican vs. Democrat thing going on with me here.
The problem I'm having right now is that John McCain's public pronouncements and voting record suggest four more years of the very hijacking of the Republican Party you deplore. We truly cannot afford that.
There is another factor, as well. Bush and his cronies have done many, many things that are - to put it as politely as possible - rather questionable, in both legal and moral senses. We need both investigation of the charges that have been levelled at the Bush administration, and we need to restore some things to where they were before Bush and his cronies began tinkering with them. If we do not, dangerous precedents will have been set for Presidential abuses of power.
Since McCain's base is also largely Bush's base, I don't think we can expect much in the way of investigations if McCain is elected. And I think that's very bad for the country, because if there's one thing we know, it's that politicians are not going to get more fair-minded and moral as the years go by. If no one investigates and brings wrongdoers to some sort of justice, the precedents set during the Bush years will give future power-grabbers quite a lot of latitude to expand upon Bush's "Imperial Presidency" style of running things.
This is asking a lot of any Republican, and I know it, but I hope you'll think hard about what a continuation of Bush's policies and ethics might do to America. Electing Obama is, frankly, not what I want this country to do, but at least we'd stand some chance of curbing those elements in the Republican Party you deplore. With McCain, I honestly do not see that happening.
I hope you will take this as reasoned discussion, not as "I'm right - you're wrong" stuff. There's way too much of that on the Web already. I've been very capably led by Republicans for much of my life (I remember Ike and Gerald Ford with especial fondness), and I, like you, would like to see that kind of Republican come back in style.
