I don't know a lot about US elections, but here's an obvious thing to check, and that's voter turnout.

2012 58.6%
2026 57.3%
2020 66.6%
2024 - not finally available, and chart presented without final voting count is making the comparison slightly worthless.

The turnout for this year's election is predicted to be about 2 % lower than 2020. That's around 3 million votes. So that alone will go some way of correcting this graph as we wait for further votes to be counted. . And the two earlier elections show a relative loss of around 14-16 million votes c/w 2020. That's accurately shown in the graph provided and proves absolutely nothing about Biden's vote in 2020. And why does the graph show the votes for the winners earlier, but Harris was the loser. of course she has less votes. Nor is it explained how the Democrats could run such a clever successful vote rigging machine in 2020, and somehow fail to be able to be clever enough to pull the same stunt today.

This is total nonsense, but around three quarters of Republican voters belief Trump was robbed of victory by electoral fraud in 2020. All this graph shows and the stupid article that's been posted is how ridiculous the US is as a state, and how troubled and how near to failure it's likely to be.
