Are you saying that what many Democrats endorsed Bush to do wasn't war?
1. what was authorized was based on a fraud perpetrated by bush/cheney
2. what was authorized was that the president have everything at his disposal to enable effective diplomacy.
3. before baby bush was allowed to wage war, he was supposed to listen to the final report of the UN inspector (which he intentionally ignored);
4. he was supposed to exhaust diplomatic efforts and then GO BACK TO CONGRESS
you really should read the iraq resolution.
