You know, after the debacle that was the Bush vs Kerry election, there were widespread allegations by Democrats of voting fraud on the part of the Republicans -- especially in respect to electronic voting machines. For some months after the election, the Democrats made a lot of noise about those electronic voting machines, trying to get them removed. After a few months, they apparently seemed to forget all about it.

When the next election rolled around, when Obama won, they didn't make a peep about the electronic voting machines, which were still in use, nor about the possibility of voting fraud. Neither did the Republicans. Nor did anyone mention these issues in the following election, when Obama won again. It was only Trump speaking up about it which brought the issue back in to the news. But the possibility of massive voting fraud has been there all along, and will continue to be there for the following elections, as long as electronic voting machines are still in use.

Now, why does the mainstream of both the Democratic and Republican parties permit these machines to continue to be used? That's a very good question. The consipracy minded might speculate that they might have an agreement between them, and that US elections have become simply political theater, with the real decisions as to who gets to hold office being made through other means, and by people other than the voters.
