JACKSONVILLE, Fla. – Incumbent Marco Rubio (R) has increased his statewide lead over Democratic challenger Patrick Murphy by four points in the Florida Senate race, according to recent data from Mason-Dixon Polling & Research.

In August, prior to the state primary elections, Mason-Dixon Polling & Research data showed that Rubio had a 46-43 percent advantage over Murphy. Their most recent poll shows Rubio now holds 47 percent of statewide votes, while Murphy has dropped to 40 percent.

Libertarian candidate Paul Stanton remains in third place with five percent of votes, while six percent of the participants indicated that they were undecided on who to vote for if the election had been held the day they were polled.

According to the Mason-Dixon poll, Senator Rubio’s strongest region of support is seen in North Florida, where he holds 56 percent of the vote compared to Murphy’s 32 percent. Murphy’s strongest area of support was seen in Southeast Florida, respectively, where he holds 53 percent over Rubio’s 37 percent.

Of the participants who recognized Rubio’s name, 45 percent of them said they had a favorable opinion of him, while 34 percent said they had an unfavorable one.

Twenty-seven percent of the participants who recognized Murphy’s name said they had a favorable opinion of the Democratic candidate, while 25 percent said they had an unfavorable opinion of him. Interestingly enough, 33 percent stated they had a neutral opinion of the challenger.

Seventy-eight percent of the participants had no name recognition of Stanton, while 15 percent didn’t recognize Murphy.

According to Mason-Dixon research, Rubio’s favoritism among the Hispanic demographic is enabling him to pull approximately 16 percent of Democratic votes from Murphy. The overall importance of the Hispanic vote in the swing state makes it increasingly difficult for a Democratic candidate to win unless they garner the support of that demographic.

Another demographic of interest in the Senate race is sex. Rubio holds more favoritism among men, while Murphy has a slight advantage over the incumbent among women.

This Mason-Dixon Senate race poll was conducted from Sept. 27 through Sept. 29. It was based on a total of 820 registered Florida voters, all of whom indicated they were likely to vote in the November general election. The margin of error was plus/minus 3.5 percent.
