Democrats today released a poll showing Marco Rubio and Patrick Murphy in a virtual tie and argue that Murphy has room to become better known to voters across Florida.
The poll conducted for Senate Majority PAC, which is supporting Murphy, shows Murphy with 45 percent of the vote to Rubio's 44 percent and 9 percent of voters undecided.
The Real Clear Politics average, which does not include this poll, has Rubio leading by 5.7 percentage points.
Civis surveyed 1,463 people by landline and cell phone from Aug. 9-15. The poll has a margin of error of +/- 2.8 percent.
"There is substantial opportunity to grow Murphy's vote share with groups where we expect support to coalesce after the primary and as voters become more familiar with the candidates nearing Election Day. We suspect that there is not yet Democratic consolidation due to this survey being conducted before the primary," reads a polling memo prepared by Civis Analytics.
It said Rubio's favorability had declined 9 points since he announced he would run for re-election.
"Rubio is already a well-known candidate in the state and is likely at his ceiling. In contrast, Murphy has room to grow among several Democratic leaning groups that should be responsive to communications. He is well positioned to win this seat in the fall."
