Many of the studies done polling how many Republicans support the birther movement have been done by liberal or Democratic party affiliated polling firms. So it’s hard to trust them.
Some on CBS show far less support for the birther movement at only 20% which still sounds high and CNN which shows more.
I’d like to see the opinions of conservatives, independents and Republicans on this. I don’t know any Republicans who believe this idea. It also seem to be used as a tool by Democrats to make undecided voters angry at the Republicans.
