Less than a week after filing papers to run, former North Miami Mayor Kevin Burns announced at Wednesday’s Democracy for America meeting in Coral Gables that he is ending his campaign for the U.S. Senate and will instead run for the state Senate seat that Dan Gelber, D-Miami Beach, is vacating to run for attorney general.

While billionaire Jeff Greene has been in the Democratic primary for the U.S. Senate for less than a week, he has already shaped the race tremendously --forcing Congressman Kendrick Meek to focus on his new rival instead of on newly independent Gov. Charlie Crist or former House Speaker Marco Rubio, the likely Republican nominee.
