The Invisible Primary, 8/12

Tracking the GOP race to 2012

It appears Rick Santorum is testing the waters for a 2012 run--he's scheduled a trip to Iowa in October; according to a new CNN/Opinion Research poll, Sarah Palin's favorability ratings have dropped significantly, from 48 percent to 39 percent; Eric Cantor criticized U.S. foreign policy during his trip to Israel; the DCCC used Sarah Palin and Newt Gingrich to raise money; and Mitt Romney leads his putative opponents by a lot in a new poll of New Hampshire voters, collecting 50 percent of support (Palin and Mike Huckabee get 17 percent).
