Boosted by a recent influx of cash of an unknown amount and origin, an independent super PAC that supports Democratic U.S. Senate candidate Patrick Murphy is launching a TV ad that will air in Murphy's backyard between now and Election Day.
"Floridians for a Strong Middle Class" announced the ad Monday morning, which touts newspaper editorial endorsements Murphy has received from the Miami Herald, Tampa Bay Times, Orlando Sentinel and Sun Sentinel. Each editorial included harsh criticism for Republican incumbent Marco Rubio, which the ad also emphasizes.
In response to the ad, Rubio campaign spokeswoman Olivia Perez-Cubas said Murphy has "nothing to show" for his four years in Congress and argued the senator "has a strong record of fighting for Florida's families."
The super PAC says it's spending $800,000 to run the ad for the next two weeks on West Palm Beach stations -- a TV market that serves Murphy's moderate congressional district in northern Palm Beach County and the Treasure Coast.
That area should hypothetically be safe territory for the Jupiter congressman since Palm Beach County is heavily Democratic and more-moderate Treasure Coast voters helped elect Murphy to Congress for the past two cycles.
Ashley Walker, spokeswoman for "Floridians for a Strong Middle Class," told the Herald/Times: "Patrick Murphy has a strong record of independence in this district in terms of doing what's right for his constituents, and this ad reinforces that message."
As of Sept. 30, "Floridians for a Strong Middle Class" didn't even have $800,000 in the bank to spend, but Walker said "obviously some contributions have come in" since then.
Heading into October, the super PAC reported having $764,000 in cash on hand in its third-quarter disclosure report. Walker said the recent donations will be disclosed in the committee's pre-general election report, which is due later this week.
Between July and September, the super PAC reported raising about $1 million between July and September -- a haul that included a $250,000 check from Murphy's father, Tom Murphy Jr. (Tom Murphy had also previously given $500,000 to the committee earlier in the campaign.)
