People can argue about the functionality of the software, ballot harvesting, illegal ballots, suspicious late night counting, duplicated votes flipped by poll workers, absence of oversight in PA and late night deliveries. Or, the most egregeous example I've seen, of ballots stored in bags and then returned for counting in boxes and of course the statistical blips and turnout data between similar states favouring biden.
Pennsylvania - The article 2 will pass SCOTUS and that state will struggle to hold the line before flipping.
Arizona - Looks very dicey for the DNC, at the moment.
Georgia - The evidence is the first I've seen, but that state similarly looks very dicey for the DNC.
Michigan - The DNC lead may well be enough.
Wisconsin - Is a very odd, closed state and I expect the SCOTUS may well take a look at that one as well.
Summary:-
The anti-trumpers may well still hold the ground and time is running out, as the electoral college could well still give Biden the Presidency. But isn't the worst of scenarios for people who support democracy that Biden is given the job and the evidence of fraud really does start to emerge out of the swamp ?
