No, really. It's totally OK for you to give up on Obama. It's your right; it's even your moral duty to do so if you think it's necessary. And don't feel guilty about it, either. Obama doesn't even miss you; heck, he wants you to quit. Nothing convinces the Center he's on their side like the sight of a bunch of Lefties squealing in outrage.
But next year, when it comes time to make political donations and decisions, take a clear, cold-eyed look at your choices. Pick the one that is in your best interest. Vote for the best deal you can get for yourself. That is your civic, moral duty, and that's all we're asking for.
