Well, as usual, we have members of this site saying they won't/might not vote for the Democratic candidate for President of the United States.
It happened in the primaries, with mainly Obama supporters saying they wouldn't vote for Clinton if she became the nominee.
Clinton, and now Obama failed a "purity test" to some people.
To quote New York Mayor Ed Koch has often said that a one-issue candidacy isn’t sufficient to run on. "If you agree with me on 9 out of 12 issues, you should vote for me," Koch often has said. "If you agree with me on 12 out of 12 issues, you should see a psychiatrist."
So Obama is running towards the center or right during the GE. SO WHAT? He is going to have a Democratic House and Senate. With proper leadership there, we will be able to pass progressive legislation there, and Obama will sign it.
He will say, just like with the FISA Bill, it's not perfect but good enough to sign. He will have his cake (progressive legislation), and be able to eat it (claim he is more moderate than the legislation)
The next President will likely appoint at least two SC Judges to replace retiring/ill/deceased members who are the liberal votes now. So imagine 6 Scalias, or Six Thomases, Alitos, or Roberts deciding cases. Hell, they might declare income taxes unconstitutional. That will bankrupt the country, or at the very least shift even more of the burden onto the lower income people. Say goodbye to anything resembling affirmitive action. Kiss equal pay for women goodbye for 50 years or more.
Do you want the Bushco crimes investigated? DEFINITELY will NOT happen if McCain is President.
Sure, Obama has flaws. So did Edwards, Clinton, and the rest of the Dem candidates. He's OUR nominee now. If you don't vote for him, we all may pay the price.
