Santorum is not a reliable conservative on economic/fiscal issues. He’s a big government “compassionate conservative” ala George W Bush. No thank you.
RINO Rick can no longer skulk in the background and take potshots at Newt when Newt is clearly out gunned financially. Newt always seems to gain during times like this.
Santorum is not perfect but he and Gingrich are very close in terms of fiscal issues - earmarks, balanced budget amendment, tax reform, Medicare Part D. One could argue that Santorum's platform for aggressive entitlement reform and Newt's attack on Ryan's entitlement reform makes Santorum far superior - but let's say they're on the same page generally. If you oppose Santorum for fiscal reasons, you oppose Gingrich as well.
That leaves favoring a brokered convention - which involves both Santorum & Gingrich succeeding in the primaries - or Mitt, or Ron Paul. Which do you prefer?
