From today's Sun-Sentinel, the main daily out of Ft. Lauderdale, FL:

Voter registrations in Florida show 'huge swing' toward Democrats

Pertinent quotes:

An escalating number of voters registering as Democrats is providing evidence that the 2008 election could produce a wave of support ... trigger[ing] a decades-long shift of party allegiance that could effect elections for a generation.
...
Democrats have posted even greater gains statewide, up 106,508 voters from January through May, compared with 16,686 for the Republicans.

"I'm excited to vote for whoever is running for the Democrats," he said.  "I don't have much of a choice.  I don't really like the other party."

Michael Martinez, an associate professor of political science at the University of Florida, said there aren't many people shifting from the Republicans to the Democrats.  But the allegiance of first-time voters is significant.

"New voters tend to identify with the hot party at the time.  In the 1980s, a lot of new voters were identifying with Reagan, because he was sort of the hot commodity," Martinez said.

Just a heads up to those who might be interested.  Obama will be interviewed by Zakaria on his CNN show GPS.  It starts at 1:00pm ET.  The CNN episode summary:

An exclusive interview. Senator Barack Obama answers the tough questions on the world's greatest crises, from Iraq to Afghanistan, from Israel to Iran. Don’t miss what promises to be one of the best interviews of the year!

I haven't seen Zakaria's show before, but based on his writing I'm assuming it'll be a fairly substantive discussion.  Should be good watching.
