Democratic Senate candidate Rep. Patrick Murphy (Fla.) is getting a major financial boost as his campaign heads into the final stretch before the Florida primary, courtesy of a $1 million check from his father. 

Thomas Murphy, a Florida homebuilder, gave the seven-figure sum to Senate Majority PAC — the group's largest donation in July, according to the Federal Election Commission.
The congressman has long benefited from his father's financial largesse; Thomas Murphy shelled out six-figure super-PAC contributions to help Patrick Murphy win his Florida congressional seat in 2012.
On July 15, two days after the $1 million check landed in the Senate Majority PAC account, the super-PAC announced to The Washington Post its plan to launch a $1 million ad buy in Florida. 
The Washington Post noted that the ad buy was an unusually early intervention for the leading Democratic Senate super-PAC, saying the $1 million buy was "its first-ever television ads in a Democratic primary, as it seeks to shepherd a top recruit through a competitive intra-party contest."

He could use his father's extra cash to help narrow Rubio's lead of about 6 percentage points. Given it's a super-PAC donation, the money must be spent without coordinating with Murphy's Senate campaign.
