As of this moment, Romney, one of John McCain’s chief rivals for the 2008 Republican presidential nomination, holds a slight but not statistically significant 26% to 21% advantage over Palin, who was McCain’s vice presidential running mate.

Palin’s strong showing suggests she remains a contender for GOP front-runner status even after her surprising decision to resign as governor of Alaska, which she announced July 3. Some have speculated that she made that decision with an eye toward running for president in 2012.
