INDIANOLA, Iowa — Given the hubub ahead of Sarah Palin’s speech today, turnout at the Tea Party of America’s “Restoring America” event isn’t as big as anticipated.

Perhaps 500 people are braving the on and off rain showers ahead of the former Alaska governor’s keynote address.

Palin’s One Nation tour bus is parked in the grass in front of the stage. She’s due at the mic in just under an hour.
