WASHINGTON (CBS/AP) — The Supreme Court has rejected Republicans’ last-gasp bid to reverse Pennsylvania’s certification of President-elect Joe Biden’s victory in the electoral battleground. The court without comment Tuesday refused to call into question the certification process in Pennsylvania.

Gov. Tom Wolf already has certified Biden’s victory and the state’s 20 electors are to meet on Dec. 14 to cast their votes for Biden.

Biden won 306 electoral votes, so even if Pennsylvania’s results had been in doubt, he still would have more than the 270 electoral votes needed to become president.

Meanwhile, earlier Tuesday, President Donald Trump’s campaign lost another round in a flurry of Republican lawsuits over Pennsylvania’s election, with the state Supreme Court refusing to hear its appeal over fewer than 2,000 ballots in a suburban Philadelphia county.

The court, which has a 5-2 Democratic majority, denied the emergency appeal request in a one-line comment that did not explain the decision.

There are at least five other pending cases in which Trump or Republicans are trying to throw out certain ballots or trying to upend President-elect Joe Biden’s victory in Pennsylvania over Trump by more than 80,000 votes.

The Bucks County case involves 1,995 mail-in ballots in which voters failed to handwrite their name, address or date on the outside ballot-return envelope, or enclosed their ballot in an inner unmarked secrecy envelope that became unsealed.

The Trump campaign maintains the ballots should be thrown out under state law.

The state Supreme Court, ruling in separate cases from separate counties, has refused previous Republican requests to throw out ballots for lack of a handwritten name, address or date on ballot-return envelopes.

Bucks County’s election board chose to count the ballots, a decision that was upheld in lower courts. The county’s lawyers contended that Trump’s campaign shouldn’t be allowed to appeal.

The Trump campaign’s request was procedurally flawed because its claims about constitutional violations weren’t submitted to the trial court and, in any case, the number of ballots in question are far too few to overturn Biden’s win, county lawyers argued.

Trump narrowly won Pennsylvania over Hillary Clinton in 2016.
