Ignoring the obvious flaw of throwing out the importance of infinity here, they would be exceedingly unlikely but technically not unable. A random occurrence is just as likely to happen on try number 1 as it is on try number 10 billion. It doesn’t become any more or less likely as iterations occur. This is an all too common failure of understanding how probabilities work.

True, it’s not exactly like they care about real proof.

While this is a shit move by whoever is doing this, it makes virtually no difference for the presidential election. WA electoral votes are winner-takes-all, and always go Dem. A few burned boxes won’t come close in making a difference for president, Biden won by almost a million votes in the last one. It will probably have a decent effect on local elections though.
