Two Florida congressmen are running neck and neck in the Democratic primary to replace U.S Sen. Marco Rubio, R-Fla., in 2016, a new poll shows.
On Monday, Mason-Dixon released a poll which finds U.S. Rep. Alan Grayson, D-Fla., ahead of U.S. Rep. Patrick Murphy, D-Fla., by a whisker in the primary: 33 percent to 32 percent. But a plurality of those surveyed -- 35 percent -- remain undecided.
