MIAMI — Air Force One just landed here as President Obama prepares to attend a fund-raiser in Miami Beach for Democratic Senate and House candidates.

Obama stepped off the plane about 5:30 p.m. with Sen. Bill Nelson and greeted a passel of Democratic elected officials on the tarmac at Miami International Airport: Chief Financial Officer and gubernatorial candidate Alex Sink; U.S. Rep. and Democratic Senate frontrunner Kendrick Meek of Miami; U.S. Rep. Debbie Wasserman Schultz of Weston; Miami Mayor Manny Diaz and state Sen. Dan Gelber of Miami Beach.

Obama is to attend a fund-raiser at the Fountainebleu Hotel, then go to a solar energy plant in DeSoto County on Tuesday.

Here are two names getting floated as Democratic CFO candidates: former Congressional candidate Annette Taddeo of Pinecrest and Miami Mayor Manny Diaz.

Republican Jeff Atwater made his candidacy official this morning in the race to replace state CFO Alex Sink, a Democrat, who said Wednesday that she’s running for governor in 2010.

Taddeo lost to U.S. Rep. Ileana Ros-Lehtinen, R-Miami, 58 percent to 42 percent in the 2008 general election, but earned a reputation as a hard worker and smart campaigner among some Democrats. The founder and CEO of LanguageSpeak, a company that provides translation services in 100 languages, she was also reportedly a candidate to run the Small Business Administration under President Obama.

Diaz was first elected Miami mayor in 2001 and is currently president of the U.S. Conference of Mayors. Diaz supported Hillary Clinton for the Democratic presidential nomination last year, but ultimately endorsed Obama and addressed the Democratic National Convention in Denver.
