Who Are The Most Influential Conservatives?

A conservative website provided its list of the 25 most influential conservatives.  Most of them are in the media and are well known.  Some of you may be curious about the list but I posted it for another reason.  Can you name the 25 most influential progressives?  I'll bet that you will find it difficult to come up with 25 names, and that you could add others to the top 25 conservative list.  That may explain why the GOP has moved so far to the right.  The Tea Party has not been an accident.
