Alan Grayson may have a slight lead over Patrick Murphy, but nearly 40 percent of likely Democratic voters are still undecided when it comes to their top choice in the U.S. Senate primary.
According to a new Targeted Persuasion survey, 30 percent of likely Democratic primary voters said they planned to vote for Grayson in the Aug. 30 primary. Twenty-seven percent of voters polled said they supported Murphy; while 5 percent said they planned to vote for Pam Keith.
While Grayson has a slight lead over Murphy, the survey found 38 percent of respondents said they still are undecided.
According to the polling memo, Grayson leads Murphy among African-American voters and Hispanic voters. Murphy, according to the memo, leads among white male and female voters.
The survey found 73 percent of respondents had at least a favorable opinion of Hillary Clinton, the presumptive Democratic nominee.
President Barack Obama is well-liked among Florida Democrats, with 86 percent of respondents said they had a favorable or very favorable opinion of the president. That could bode well for Murphy; the president has cut a statewide radio advertisement for him.
Both Obama and Vice President Joe Biden endorsed Murphy in March.
The survey of 862 likely Democratic primary voters was conducted from June 14 to June 16. It has a margin of error of 3.34 percent.
