A new poll out by Suffolk University's Political Research Center today shows Republican incumbent Sen. Marco Rubio up by at least 13 percentage points on either of his likely Democratic opponents in November's election for Florida's U.S. Senate seat.
In a match-up against Democratic U.S. Rep. Alan Grayson, Rubio leads 45 percent to Grayson's 31 percent, with about 22 percent undecided and 2 percent who didn't answer. Against Democratic U.S. Rep. Patrick Murphy, Rubio's lead narrows by 1 percentage point; he led 46 percent to Murphy's 33 percent, with about 19 percent undecided and 2 percent who didn't answer.
Suffolk University surveyed 500 likely Florida voters by telephone between Aug. 1-3. The margin of error is plus or minus 4.4 percentage points.
Florida's U.S. Senate race has garnerned national attention and millions of dollars in political spending because the election could decide which party controls the chamber next year.
The university's polling results further solidify Rubio's status as the front-runner in the Senate race, especially within his own party primary.
Of the 165 people polled who planned to vote in the upcoming Republican primary, 62 percent said they would vote for or were leaning toward Rubio, while his main challenger Carlos Beruff got 12 percent support. About 24 percent remained undecided and 1 percent didn't answer. Lesser-known candidates Dwight Mark Anthony Young and Ernie Rivera got 1 percent and 0 percent support in the poll, respectively.
In the Democratic primary, "undecided" was in the lead -- as it has been in many polls for months -- followed by Murphy.
About 40 percent of the 168 likely Democratic primary voters surveyed said they didn't know yet who they'd vote for -- even as some ballots have been mailed out already and there's less than a month until the election.
Murphy got about 36 percent support, followed by Grayson with 17 percent. Pam Keith received about 2 percent support, while newer candidates Reginald Luster and "Rocky" Roque De La Fuente were tied with around 1 percent support. (Two percent of respondents didn't answer.)
Both the Democratic and Republican primaries for Florida's U.S. Senate race are Aug. 30. The winners will face each other in the November election.
