A new ad from a nonprofit group has called Sen. Robert Casey (D-PA) a "sore loser" for his refusal to concede the recent election to Republican challenger Dave McCormick and pointed out that Democrats were quick to label their Republican opponents including Donald Trump "election deniers" for doing the same thing in previous elections.

“Casey and the Democrats are sore losers. And they’re disrespecting our democracy,” a female narrator says in the ad from the Fair Election Fund, a group founded only in May to fund and protect whistleblowers who report election irregularities.

The ad criticizes Casey's “hypocritical refusal to concede the election." Casey has continued to fundraise with an insistence that every vote be counted even though he'd have to win over 70% of the remaining votes in counties he barely won or that he lost in the counting so far.

A win is extraordinarily unlikely, so much so that the Associated Press called the race for McCormick last Thursday. McCormick leads by 35,000 votes in the state.

Running up taxpayer costs

Casey's tactics could trigger an automatic recount that would cost taxpayers $2 million even though it's extremely unlikely Casey would win such a revote.

Casey was very vocal in calling for then-President Donald Trump to concede to President Joe Biden in 2020, but now the tables have turned and he's not so willing to concede himself.

“But now that he’s lost, he’s changing his tune,” the ad’s narrator says. “They’re denying the results and trying to force an unnecessary recount using your tax dollars.”

“Tell Bob Casey: It’s time to concede," the ad finished.

The fund has spent hundreds of thousands of dollars on the ad, mostly in and around Harrisburg, Philadelphia and Scranton.

McCormick attended the Senate orientation on Wednesday at the invite of current Majority Leader Chuck Schumer (D-NY). Schumer almost excluded McCormick because the race wasn't completely finalized, but later changed his mind after pushback and invited Schumer and Ruben Gallego, an Arizona Democrat whose race was also called by the AP but not conceded by his opponent Kari Lake.
