Martinez's decision was based on a desire for more free time and a less scheduled life, said the source. The first term senator also was an almost certain Democratic target in two years time although those familiar with Martinez's political prospects insisted his strengths in South Florida, coupled with his political base along the I-4 corridor, made his path to reelection possible.
Martinez's retirement ensures a competitive and costly open seat race in Florida. State Chief Financial Officer Alex Sink, widely seen as Democrats' strongest potential candidate, has apparently decided that she would not run but may well reconsider that decision given Martinez's expected announcement today. Democratic Reps. Ron Klein and Kendrick Meek as well as state Sen. Dan Gelber are likely to consider the open seat race.
On the Republican side, there may well be a push to recruit former Gov. Jeb Bush into the contest although that seems like a long shot. State Attorney General Bill McCollum will almost certainly be mentioned as will state Senate President Jeff Atwater and former state House speaker Marco Rubio. Reps. Vern Buchanan and Connie Mack also may consider a run.
