Conservatives are intellectually curious and seek information from sources they trust.....Rush, Beck, etc
Liberals are not intellectually curious, hence they do not even want to listen to those who espouse similar views for fear of hearing something that does not fit with their world-view.
Liberals have a bumper sticker mentality but the one that truly applies to them is “Ignorance is Bliss.”
I recently talked with a “Newsweak lib” that hadn’t even heard of the “flag@whitehouse.gov” fiasco.
