The state of Penn­syl­va­nia cer­ti­fied its elec­tion results Tues­day, as Gov. Tom Wolf signed off on the slate of 20 elec­tors and solid­i­fied Pres­i­dent-elect Joe Biden’s vic­to­ry in the state where he was born, one of the most hot­ly con­test­ed prizes of the election.

The move in Penn­syl­va­nia, a state that Biden won by more than 80,000 votes, fol­lows the cer­ti­fi­ca­tion of the results in Michi­gan on Mon­day and Geor­gia on Fri­day. All three were states that Pres­i­dent Don­ald Trump won in 2016 and Biden flipped.

With mul­ti­ple bat­tle­ground states that Biden won now hav­ing cer­ti­fied their results, the flail­ing effort by Trump and his allies to sub­vert the elec­tion and over­turn the votes of mil­lions of Amer­i­cans is near­ing its end.

In Penn­syl­va­nia, the Trump cam­paign and Repub­li­can allies had tried to halt the cer­ti­fi­ca­tion for weeks through a flur­ry of lit­i­ga­tion, yet were con­stant­ly rebuffed by judges who found the effort lacked any evi­dence of fraud. The cam­paign had most recent­ly asked the 3rd U.S. Cir­cuit Court of Appeals to block cer­ti­fi­ca­tion in Penn­syl­va­nia. But some legal experts have argued that if Penn­syl­va­nia offi­cial­ly cer­ti­fied its results before the court made a deci­sion, the case would be con­sid­ered moot.

Wolf, in announc­ing the cer­ti­fi­ca­tion, praised the elec­tion work­ers in his state who had faced harsh crit­i­cism and harass­ment as the pres­i­dent con­tin­ued his effort to sub­vert the election.

“I want to thank the elec­tion offi­cials who have admin­is­tered a fair and free elec­tion dur­ing an incred­i­bly chal­leng­ing time in our com­mon­wealth and country’s his­to­ry,” Wolf said in a state­ment on Twit­ter. “Our elec­tion work­ers have been under con­stant attack and they have per­formed admirably and honorably.”

Mul­ti­ple coun­ties across Penn­syl­va­nia had cer­ti­fied their results Mon­day amid some scat­tered efforts by local Repub­li­cans to halt the process.

In Alleghe­ny Coun­ty, the sec­ond-largest coun­ty in the state and home to Pitts­burgh, the board vot­ed 2–1 to cer­ti­fy the results, with Sam DeMar­co, the lone Repub­li­can mem­ber, vot­ing against. DeMar­co said his vote was an attempt to spur action in the state cap­i­tal to make changes to the state’s vot­ing laws, The Pitts­burgh Post-Gazette reported.

In Luzerne Coun­ty, which Trump won by more than 14,000 votes, the board cer­ti­fied the results in a 3–2 vote, again with the Demo­c­ra­t­ic mem­bers of the board vot­ing to cer­ti­fy and the two Repub­li­cans vot­ing against.

The state had been specif­i­cal­ly tar­get­ed by Rudy Giu­liani, the for­mer may­or of New York and per­son­al lawyer to the pres­i­dent, who repeat­ed­ly made base­less alle­ga­tions of wide­spread fraud. Short­ly after the elec­tion, Giu­liani deliv­ered a now infa­mous news con­fer­ence at Four Sea­sons Total Land­scap­ing in north­east­ern Philadel­phia, false­ly declar­ing that the city’s elec­tion had been marred by fraud and obstruc­tion. Numer­ous judges would lat­er reject those claims in court.

Although Wolf had cer­ti­fied the results in the state, there are still some out­stand­ing law­suits regard­ing small­er amounts of bal­lots in spe­cif­ic coun­ties that need to be sort­ed, though they will have no sig­nif­i­cant effect on the pres­i­den­tial margins.

In the days fol­low­ing the elec­tion, Penn­syl­va­nia became the cen­ter of atten­tion, as mul­ti­ple coun­ties worked around the clock to process thou­sands of absen­tee bal­lots, pro­vid­ing incre­men­tal updates to the over­all vote total that saw Biden slow­ly eclipse Trump and even­tu­al­ly build a sig­nif­i­cant lead, near­ly dou­bling Trump’s 2016 mar­gin in the state.

One of the chron­i­clers of the vote swings was Sen. Bob Casey, D‑Pa., who would post video updates of his analy­sis of the vote.

On Tues­day, after Wolf announced the cer­ti­fi­ca­tion, Casey sighed, tipped an open beer from the local brew­ery Vic­to­ry Brew­ing toward the cam­era, and took a sip.
