A Quinnipiac University poll released on Wednesday morning shows Sen. Bill Nelson, D-Fla., and Republican Rep. Connie Mack running neck-and-neck. Nelson leads Mack 41 percent to 40 percent with 17 percent of voters undecided.
The survey is the latest in a string of recent polls revealing a tight race in the Sunshine State. The previous poll, conducted earlier this month during a period ending one day before the latest poll was started, showed a nearly similar spread, with Nelson leading Mack 43 percent to 39 percent.
The poll also found a tight contest in the presidential race. Among Florida voters, President Obama outpaces Mitt Romney 45 percent to 41 percent, according to the poll. Nine percent of voters said they are undecided on the White House race.
Mack significantly outperforms Romney among Hispanic voters in the poll. While Obama leads Romney 56 percent to 32 percent among Hispanics, Mack only trails Nelson by 2 percentage points - 37 percent to 35 percent. Twenty-five percent of Hispanics are undecided in the Senate race, compared to just 10 percent in the presidential contest.
Mack, the son of former Sen. Connie Mack III, is the heavy favorite to win the GOP nomination. Former Sen. George LeMieux dropped out of the race last week, but former Rep. Dave Weldon and retired Army Col. Mike McCalister are also running in the August 14 primary.
The Quinnipiac poll, which was conducted June 19 through June 25, surveyed 1,200 Florida voters and has a margin of error of plus-or-minus 2.8 percentage points.
