All three also support Newt Gingrich. None have endorsed anyone, but there is no doubt all three would support Newt with a full court press.
But it is obvious all three prefer Perry,Bachman and Santorum over Newt and Mitt. Rush and Mark refer to them as the conservatives in the race.
Newt and Mitt are on record self-confessed “progressives” and even though none of the candidates are perfect that curse is the worse.
