Sort of. The birther angle does three things.
1. Energizes the far right.
2. Energizes the far left.
3. Creeps out everyone else.
This is why the all of the GOP high command, pundits, politicians, commentators and thinkers avoid this issue like a radioactive plague (and the left loves to stoke it). No Palin, no Krauthammer, no Beck, no Hannity, no Supreme Court judges, no congressmen, no senators. Nobody will touch it because it's poison. It cannot unseat Obama. It can only strengthen him.
It's not a conspiracy. It's not a mystery. It's numbers. You can quote Vattel until you're blue in the face, but this issue is a road to defeat in 2012.
See the up-thread "greater good" comments. I believe it's for this pragmatic reason no one wants to touch it. Not to mention probable GOP marching orders.
