The field for Senator Mel Martinez’ seat is getting more crowded by the day. Yesterday, Senator Dan Gelber announced he was running. Today, Tampa’s Mayor, Pam Iorio, has announced that she’s taking a serious look at running for the seat. Iorio is considering running because no major candidate has yet emerged from the Tampa/St. Pete area which is home to nearly a quarter of the statewide electorate and typically the ideal home base for a statewide candidate, according to the St. Pete Times.
