As Pennsylvania's Senate race remains undecided a week after Election Day, Republicans are confident of victory, while Democrats hold onto hope. The race between Democratic Sen. Bob Casey and Republican Dave McCormick is close, with McCormick leading by around 40, 000 votes and about 122, 000 votes yet to be counted. McCormick has already declared victory, while Casey's campaign believes the remaining votes, especially from Philadelphia and its suburbs, could turn the tide.

Provisional ballots are a key concern. These are cast when there's uncertainty about a voter's eligibility. The U. S. Supreme Court recently ruled that voters in Pennsylvania with potentially defective mail ballots can cast separate provisional ballots in person. McCormick's campaign has challenged some of these ballots, but the case was dismissed for now.

The outcome of this race is significant. It could affect the size of the Republican majority in the Senate and influence Senate leadership elections. Currently, Republicans are set to control at least 52 seats.

Senate Majority Leader Chuck Schumer is waiting for a clear winner before inviting the Pennsylvania Senator-elect to Congress. This has angered some Republicans, who argue that McCormick should be allowed to participate in orientation and the leadership vote.

In a similar situation, Arizona Democratic Senate candidate Ruben Gallego was not invited to the orientation as his race is also too close to call.

Despite the challenges, the Casey campaign remains optimistic. They point out that in the 2022 Senate race, provisional ballots favored Democrat John Fetterman by 76%. However, they don't believe they need to match that exact percentage to win.

At the presidential level, NBC News projects that former President Donald Trump is leading Vice President Kamala Harris by about 2 percentage points in Pennsylvania.
