(CNN) - The Democratic Senatorial Campaign Committee is out Friday with its first television ad of the general election, thrusting itself into the deadlocked Senate battle between Democratic Rep. Joe Sestak and former Republican Rep. Pat Toomey.
The 30-second commercial calls Toomey "a Wall Street wheeler-dealer" and says the financial industry is "funding his campaign."
"…Millionaire Toomey helped pioneer the use of derivatives – he called them an 'enormous good,'" the ad's narrator says. "But they wound up nearly destroying our economy."
"Pat Toomey spent his whole life either working on Wall Street or working for Wall Street's interests," DSCC national press secretary Deirdre Murphy said in a statement. "The people of Pennsylvania should have a Senator who stands up for them, not the corporate special interests."
Read Toomey's response after the jump:
The DSCC does not release spending figures for its ads, nor will it say how long the ad is slated to air.
Toomey's campaign retaliated immediately, calling the spot "demonstrably false" and accusing Democrats of desperation.
"It is a sign of how desperate Sestak's Washington friends are that they feel the need to swoop in to save liberal Joe Sestak's flailing campaign with ads filled with distortions and out-right lies," Toomey Communications Director Nachama Soloveichik said.
Sestak and Toomey each have 43 percent of the vote according to latest Quinnipiac University poll, conducted July 6-11. Twelve percent are undecided. The poll had a 2.7 percent sampling error.
