This is pretty big. Many people liked Perry but were afraid of him debating with Obama. They like his ideas and his character, so him backing Newt will help ease their minds for Newt.
Also in Virginia we’ll all need to vote for Ron Paul so that Romney doesn’t get the delegates. And it may help keep Paul from running 3rd party.
Paul has my silent vote in the VA primary, but I won’t go as far as a bumper sticker or yard sign.
