As early voting begins, the state elections office released new registration figures that show Democrats now have a 658,000 vote advantage over Republicans in Florida. Since the last presidential election, Democrats have registered more than twice the number of new voters than Republicans.

And now that Florida is officially open for business, you better believe the campaigns are on the ground:

The McCain campaign is being represented by Meghan McCain, the senator's daughter. She's holding a series of events in central Florida.

Meanwhile, the Obama campaign is blanketing the state with events from Miami to the panhandle. Barack Obama and company — including Michelle Obama, Sen. Hillary Clinton, and New Mexico Gov. Bill Richardson — are holding voter rallies. At some events, they'll be joined by Republican Sen. Mel Martinez.

Polls show Obama with a lead here in Florida — a state that went for George W. Bush in 2000 and 2004.
