Because beating incumbents in the Senate, from Florida, has always been a breeze? This is never easy -- especially in Florida. With your allies in the media working hard to depict your liberal track record as being moderate, the task becomes even more daunting - with or without the support of your party. You're just plain wrong here.
I can think of four FL senators who lost reelection: Claude Pepper in the Democratic primary of 1950 (to George Smathers), Gurney in the general election of 1974 (to Richard Stone), Stone in the 1980 general election (to Paula Hawkins), Hawkins in the 1986 general election (to Robert Graham).
