The presidential race in Florida is too close to call, but Democratic U.S. Sen. Bill Nelson holds a commanding lead in his re-election race against Republican Connie Mack, according to a new NBC News/Wall Street Journal/Marist poll.
Among likely voters, President Obama leads Republican Mitt Romney by a margin of 48 to 47 percent, which is within the margin of error. The poll was conducted Sunday to Tuesday, after a nationally televised debate that Romney is widely believed to have won.
A poll released before the debate showed Obama ahead 47 percent to 46 percent. With the Nov. 6 election less than four weeks away, the new poll shows a more clearly-defined Senate race in Florida. Nelson leads Mack, a southwest Florida congressman, by a margin of 52 percent to 39 percent, the poll said.
