I wouldn’t be bragging too much about Fred Thompson’s support. He’s joined team Soros in pimping the national popular vote.
Not to mention Fred Thompson endorsing McCain for re-election over J.D. Hayworth in the 2010 Arizona primary. (all the Fredheads who swore in 2008 that Fred's association with McCain was long over and he'd never do that again were strangely silent about that one). It was even worse than Sarah Palin's endorsement for McCain since Palin had been McCain's veep choice and owed him... Fred owed McCain nothing but helped him beat a conservative anyway.
I see Santorum's heavy endorsement from grassroots conservative activists (Levin, Beck, Malkin, Limbaugh, etc.) and lack of support from his career-politician "Senate collegues" to be a positive thing. I wouldn't want him to have Trent Lott & Orrin Hatch's support. If you're looking for evidence of which GOP candidate is "anti-establishment", this is it. Santorum was never a favorite of Republicans leaders when he was in the Senate and frequently butted heads with them because he spoke out AGAINST agreed upon "bipartisan" solutions like TARP and the Fannie-Freddie bailouts.
