You don't accept a lying Bush because he doesn't give you what you want. You'll accept a lying Obama because he does.
Yet, there is one major difference:
Many who voted for Bush and that set of "conservatives" got pissed off and turned on them, thus helping create the Obama machine.
Democrats, on the other hand, will NEVER turn on their team no matter what. We see that now. In fact, the more blatant Obama is with his lies, the stronger his team gets defending him. It really is amazing to watch.
