If this were true, Trump would have won the popular vote, not the electoral college vote.
When Trump won, there was widespread denial and re-counts and all sorts of investigation, Jill Stein, of the Green Party, had several states in the upper midwest— I think they didn’t investigate Pennsylvania.
There were even democrats and others, funded by George Soros and the Clinton foundation, that attempted to pay the fines if state delegates would vote differently than their electoral colleges indicated—but even this would not have changed the outcome. You can’t buy an election.
We know voter fraud occurs and is far from rare. It is sometimes investigated on site at poling places In 2009, someone voted in my name and even signed a paper saying that they were me. I even saw the paper and signature. Whereas I DID get to vote that day, chances are whoever voted fraudulently did not vote as I would have, so that fraudulent vote was an extra vote that ‘de facto’ nullified or neutralized my vote.
Trump did very well all over the U,S, except New York and California, I have seen maps that indicate or support that a lot of the anti-Trump voting coincides with places where there are many illegal immigrants or non-citizens.
I would welcome any investigation into voter fraud and am curious why anyone wouldn’t be concerned about this issue.
