From Tuesday through Thursday this week, future senators will be presented with the ins and outs of their new jobs.

But while Republican businessman Dave McCormick is celebrating a landslide Senate victory in Pennsylvania, he wasn’t invited to the event.

The Associated Press called the race for McCormick last week, but Sen. Bob Casey, D-Pennsylvania, has not conceded the race and a recount remains possible given the close margin. As of Friday, more than 100,000 ballots had not yet been counted, but many of those could be rejected.

The ballots were primarily provisional ballots, which counties are in the process of determining whether to count, and those cast by overseas and military voters, which have until Tuesday to arrive at county election offices and be counted .

“With more than 100,000 ballots left to be counted in Pennsylvania, the race has not been decided,” a spokesman for Senate Majority Leader Chuck Schumer said in an email Monday. “As usual, we will invite the winner after the votes are counted.”

Counting of provisional votes takes place in every election, whether close or not. But the lawsuit has gained extra attention in Pennsylvania this year as the race is close and Casey’s campaign has continued to argue that the remaining ballots could swing the race.

That result seems unlikely as the candidates were separated by more than 40,000 votes as of Monday morning.

U.S. Rep. Ruben Gallego, a Democrat leading the Senate race in Arizona, has not yet been invited to the orientation — though the AP has yet to call the race, making the dynamic different from McCormick’s presumed victory.

Many media outlets rely on the AP to call races, which has a long track record of accurately declaring winners in even the closest elections. “If race callers can’t say definitively that a candidate has won, we don’t engage in speculation,” the AP says in its guide to its process.

On Thursday, McCormick spokeswoman Elizabeth Gregory said that “while the votes are still being counted,” McCormick would win “any way you slice it.”

Schumer’s party lost control of the Senate as Republicans made gains in Congress and the White House last week. Republicans spoke out against his decision to exclude McCormick on social media.

Sen. Rick Scott, a Republican from Florida who is vying to become the next majority leader, emphasized the AP’s call and said “They did the same thing to me after I beat a Democrat in 2018.” Scott, who faced a recounthe participated in his party’s leadership election but did not participate in the broader bipartisan orientation, according to his office.

McCormick’s team pointed to a social media post by the businessman saying he was looking forward to the orientation. McCormick is likely to attend Republican caucus events rather than bipartisan activities.

Casey’s campaign did not immediately comment Monday.
