Republican incumbent U.S. Sen. Marco Rubio's lead over Democratic U.S. Rep. Patrick Murphy is narrow, according to the latest poll by Quinnipiac University.
The survey, done Sept. 27 through Oct. 2, found Rubio ahead of Murphy by 4 percentage points, with 48 percent supporting Rubio and 44 percent supporting Murphy. Eight percent were undecided.
That spread is just barely within the poll's margin of error of plus or minus 4.2 percentage points, so the two could be statistically tied. The university surveyed 545 Florida likely voters in live interviews by landline and cell phones.
The last Quinnipiac poll, conducted right after the Aug. 30 party primaries, had Rubio up by 7 percentage points on Murphy.
"It looks like the battle to control the U.S. Senate will go down to the campaign's final days. The races in North Carolina, Florida and Pennsylvania could decide the matter," Peter A. Brown, assistant director of the Quinnipiac University Poll, said in a statement.
Rubio has consistently led Murphy by various margins in every poll since Rubio announced his re-election bid in June, but "his margin over [Murphy] has never been large enough to make Sen. Rubio comfortable," Brown said.
Including the Q poll announced today, Real Clear Politics has Rubio with an average polling advantage of 5.2 percentage points over Murphy.
None of Quinnipiac's polls have included Libertarian Paul Stanton or the four independent candidates who will also be on the ballot: Tony Khoury, Bruce Nathan, Steven Machat and Basil E. Dalack.
