Former Miami Mayor Maurice Ferre is expected to announce his candidacy for the Democratic nomination for U.S. Senate next week.

The 74-year-old Ferre has not served in public office for 13 years, so on the surface this would not appear to be a significant development.

However, it goes to the perception in some Democratic circles that Kendrick Meek (right) is not the strongest candidate the Dems might have next year to run against either Charlie Crist or Marco Rubio in the race to succeed Mel Martinez in the Senate.

Originally, Miami Beach State Senator Dan Gelber was in the race, but after Crist officially announced, Gelber moved over to run for Attorney General.

Meek is the overwhelming favorite to win the nomination, based on his strong union endorsements as well as heavy fundraising numbers. But some state Democrats have been grumbling amongst themselves that he won't be competitive next year.

But whether Maurice Ferre will provide any type of competition remains to be seen.
