There were a whole lot of "yeah, well", "that's not what he meant to say" and "you misunderstood" over this comment.
But the more we get to know about how corrupt he is, add to the fact that the man is going through dementia, I think he was (for once in his miserable life) telling the truth. I think the people who say he didn't mean it like that are putting words in his mouth.
He had another momentary lapse of reason and blurted out exactly what they had put together to steal the election. He probably didn't realize where he was and who he was speaking to.
The level of corruption, money and cover ups that was created, not by Biden, but by the WEF, China, Ukraine, Russia, George Soros, et al. was, as he said, "the most extensive" system to defraud the American people.
If Biden "wins" in 2024 then that will confirm that voter fraud had been committed. In 2020 most of America knew relatively little about Biden. In 2024 they know all they need to know about Biden and won't make that mistake again, not even Democrats... well... the small handful of Democrats who still use their brains. The ONLY way he can win in 2024 is voter fraud. There will be no question about it.
