Former Alaska Gov. Sarah Palin has authorized a feature-length film about her rise, added staff and recently said she has "that fire in the belly" for a presidential bid – all steps that fuel speculation she's inching toward a White House run.
Her supporters are putting together a campaign-in-waiting in Iowa, the lead-off nominating caucus, in the hopes the Republicans' 2008 vice presidential nominee decides to join the race.
There are even reports she bought a home in Arizona, not far from her daughter's, which aides have suggested could be a campaign headquarters if she goes forward.
