BREAKING: Mel Martinez Resigning

Florida Senator Mel Martinez (R) announced today that he is resigning his office due to personal reasons.

His resignation will be effective as soon as Governor Charlie Crist–also a Republican–appoints someone to serve the remainder of Martinez’s term.

Sen. Martinez previously announced that he would not seek re-election in 2010, and Governor Crist is one of the candidates running for that seat. This puts Gov. Crist in the somewhat-awkward position of having to appoint someone who will serve through 2010 but who won’t run for re-election.

While this development will not affect the partisan balance of the Senate, it’s worth noting that–with Sen. Martinez’s departure–there will be no Hispanic Republicans left in the United States Senate.
