Florida Rep. Patrick Murphy is getting a cash boost from donors and a Democratic super PAC as his campaign shows signs of life in his Senate race against Republican incumbent Sen. Marco Rubio.

Mike Fernandez, a Republican donor based in Miami, announced he would give $100,000 to a super PAC supporting Murphy, citing Murphy’s support for ending the U.S. embargo against Cuba. 

The contribution comes as the Senate Majority PAC, a group affiliated with Senate Minority Leader Harry Reid, announced it would transfer at least $1 million to the super PAC, as well.

National Democrats appeared a few weeks ago to be throwing in the towel in Florida — Senate Majority PAC previously canceled $6 million in advertising for Murphy, and the Democratic Senatorial Campaign Committee, which endorsed him against Rep. Alan Grayson in the primary, delayed pro-Murphy advertising. 

Murphy still lags behind Rubio in most polling. The latest RealClearPolitics average of recent polls gives Rubio a 3.6-point lead, though some polls have shown the incumbent with an advantage of as large as 10 points. 

The Rothenberg & Gonzales Political Report/Roll Call rates the race as Leans Republican.
