No, he isn't wrong. It's very unlikely that the recount will seriously degrade a 900 vote margin, if at all.
The article said that about 10,000 votes are yet to be counted. Considering that 900 is not an insurmountable lead.
I hope everyone knows that, a politician claiming victory, or conceding defeat, is not any legally binding statement of fact.
There is still a legal vote counting process and legal election certification procedure to occur.
Stacey Abrams is the poster girl for this. She never ever conceded having lost her election. But her not conceding had no legal effect on her election results.
McCormick should think about ‘24. Prospects are good but only if Oz wins in November. The wave could last 2 election cycles if we’re smart. Not counting on it. Sore loser-ism doesn’t work. Blow a few outside Pennsylvania and we’ll feel like those Texas cops that came up short.
