Sarah Palin has not said if she will enter the race for the 2012 Republican presidential nomination, but a growing number of GOP insiders feel she will.
Former George W. Bush adviser Karl Rove and tea party organizer Peter Singleton are both among the list of people who think she'll be in, and soon.
Rove said on "Fox News Sunday" that he would bet on it.
"Well, I'm not much of a gambler but the schedule she's got next week in Iowa looks like that of candidate, not celebrity," Rove told host Bret Baier.
Rove noted the video her PAC released Friday, which reaches out to Iowa voters. That video "strikes me as pre-presidential campaign," Rove said.
Palin is planning to speak at the Tea Party of America's "Restoring America" rally in Iowa September 3, which Singleton says could signal her entry.
