As election postmortems go, the one that began in Florida Wednesday was especially wrenching for Democrats. (AP Photo/Wilfredo Lee)TALLAHASSEE, Fla. – Perhaps only in Florida is a loss by fewer than 4 percentage points considered a public drubbing. Democrats zeroed in on two clear explanations: Biden didn't connect with the state's Latino voters, performing particularly poorly with Cuban voters in South Florida. Some Democrats also give Republicans credit for registering thousands of new voters and narrowing the voter registration advantage Democrats have long had. For Taddeo, the Democratic state senator, it means going back to basics.

State leaders eliminated computer punchcard ballots, implemented statewide recount laws and made it easy to cast and process ballots before Election Day. Though there are other scenarios that make elections officials nervous, the computer punch-card ballots that fueled 2000's chaos are buried in history's landfill. Casting valid ballots and processing them is now easier, even before Election Day, and the Legislature has enacted clearer laws governing recounts. If the statewide margin then is within a half-percentage point — likely about 55,000 votes — a machine recount would occur. These voters are notified and have until two days after the election to prove their identity, but many won’t respond.

"And Im glad to be part of that.Johnson's campaign is part of a major change in strategy for Florida Democrats. Long accustomed to being on the losing side of razor-close races, state Democrats are mounting challenges in Republican strongholds not necessarily to win but to lose by less. For years, Florida Democrats largely have focused on running up the score in heavily Democratic urban precincts in South Florida in Miami-Dade, Broward and Palm Beach counties. But Florida Democrats are hoping that enthusiasm rises from the bottom up and compounds quickly. Were fielding candidates to win races, and we think that Trump will win Florida," said Florida Republican Party Chair Joe Gruters, who is running for reelection to his state Senate seat.
