The Democrats should take Florida in 2004.
The state is registered 45% Democrat, 38% Republican and 17% 'other'.
Another way to look at would be like this:
Virtually every vote that went to Gore in 2000 will go to the Dem (Kerry, for now) in 2004.
A fair share of the 3% Nader vote from 2000 should also go Democrat.
Over 10,000 registered voters in Florida who were blocked from voting in 2000 due to being mistakenly labeled as convicted felons by then FL Secretary of State Katherine Harris will get to vote this time. I bet not many will vote Repbulican.
And I believe a small percentage (2-5%?) of those who voted Bush in 2000 will switch due to feelings of betrayal related to foreign policy and/or the incredible reversal of the federal budget from surplus to mega-deficits under Bush.
