So Obama could lose if -- and here's the big if -- Republicans do not blow the opportunity by presenting themselves as Medicare-annihilating racist maniacs... Tea Party conservatives complain that Republicans who advocate restraint, responsibility and moderation do so in order to be nice to Obama. That's utterly upside down. Restraint, responsibility and moderation are indispensable to the defeat of President Obama. It is Tea Party conservatism itself that is Obama's last, best hope for a second term.
