Actually, Jewish-Americans are the second largest voting block in the Democratic Party in Florida, and the largest voting block in Palm Beach (31% Jewish, 23% black)and Broward Counties, two of the most heavily populated counties in the state. Secular Jews dominate the state legislative delegations from the southern part of the state.
The Democratic Party has an image problem among Latinos and Anglos in Florida. To many, at least at the local level, it is seen as a party of Condo Commandos from New York (South Florida) or the "black people's party" (North Florida and the West Coast of Florida).
What is changing is the Latino/Hispanic electorate in Florida. Puerto Ricans are already the largest single ethnic group period in Osceola County (think Disney World) according to the census, and have a large presence in Orange and Volusia Counties as well. Meanwhile, the Latin population of South Florida continues to diversify, ranging from wealthy Columbians and Venezuelans in the Tri-Counties, and poor Mexicans, who are concentrated on the west coast but do not tend to vote.
The GOP has done an excellent job at courting the affluent and middle class Colombian and Venezuelan emigres, factors that may help us in places like Broward and Palm Beach, that have been Democratic strongholds over the past 25-30 years. The Puerto Rican population may be more of a problem, but their is anecdotal evidence that even they split their votes in the 2002 gubernatorial election.
I think it's rather hard for some people to believe that for a time Broward and Palm Beach were Republican from the '50s until the '70s. Anyone who has seen the movie "Porky's" can see the types of backwoods troglodyte 'Rats that once ruled those areas until the northerners came in and turned them into respectable GOP enclaves... that was until the aformentioned radical and rich leftists from NYC imported their destructive and failed politics to the area, overwhelmingly the only 2-decade old GOP areas. It's too bad we can't swap bonafide Jewish Israelis for the phony Florida JINOS. We know how the former would vote if they lived in America.
Jeb Bush's people swear that he carried Orlando-area Puerto Ricans in 2002. And President Bush couldn't have done too poorly with Puerto Rican voters from Central Florida in 2004 given that his vote precentage rose from 47.11% to 52.45% in Oceola County (in 47.6% higher turnout from 2000) and went up by 1.6% in Orange County (in 38.5% higher turnout from 2000). As you know, the Puerto Rican voters in the Orlando-area are not the "Newyoricans" you have been voting 85% Democrat since West Side Story days, but predominantly middle-class and lower-middle class Puerto Ricans from the Island who have no longstanding allegiance to the Democrat Party (especially since most are members of the pro-statehood party in Puerto Rico, which is traditionally aligned with the national Republican Party).
