Will she or won't she run for president? Former Alaska Gov. Sarah Palin, one of the most energizing and polarizing figures in American politics, has so far kept quiet about her plans.
On Sunday, she will kick off her "One Nation" bus tour, effectively putting her back in the spotlight. An upcoming film documentary and recently displayed passion to "defeat President Obama in 2012," also indicate Palin is moving toward a White House run. Her candidacy could potentially breathe life into a weak Republican presidential field.
Meanwhile, with GOP candidates Donald Trump, Mike Huckabee, and Mitch Daniels announcing they won't be entering the 2012 race, other presidential hopefuls have been moving up to the starting line.

Former Massachusetts Gov. Mitt Romney is expected to formally announce his candidacy next week.
"We picked a fine time to pick a president who had no experience in business, really no leadership experience to be president of the United States," Romney said.
Minnesota Rep. Michelle Bachmann, a Tea Party favorite, says she'll announce her plans next month.
"We want to make sure that what we are doing is deliberate and focused. We want to be prudent and responsible in the decisions that we are making," she told the Des Moines Register.
Iowa Sen. Kent Sorenson, a Tea Party Republican who would take a lead role in a Bachmann campaign, didn't have many doubts about Bachmann's decision.
"I don't think it's a matter of if she's going to run, I think it's when she's going to announce," he said. "The people in Iowa are chomping at the bit and ready for her to jump in with both feet."
Meanwhile, former Speaker of the House Newt Gingrich and former Minnesota Gov. Tim Pawlenty are already in the race.
"You have to do well or win one of those early states," Pawlenty said.
The Iowa caucuses are still about nine months away, scheduled for Feb. 6, 2012.
