The illogic of the Obamacons

Powerline has it exactly right:

An Obama administration would almost certainly be to the left of the Clinton administration. It might well be to the left of any U.S. administration ever. A person who votes to bring on that administration may be admirable in many respects. He or she may have been a conservative recently. He or she may become a conservative soon, and should be welcome in that event. But if the term "conservative" is given its ordinary, contemporary meaning, how can he or she be considered a conservative now?
