Ya know for a while I was actually on the train of thinking that Democrats always wanted to commit voter fraud and that Republicans were losing certain races b/c of voter fraud. But then at a certain point I noticed that if it was so easy for Democrats to be committing voter fraud, why wouldn't Republicans be doing the same thing?
The answer to that question isn't that Republicans are more righteous then Dems or something, it's just that it doesn't happen. I'm not even exactly sure that you'd be able to do so for the races that people are talking about. Is it possible that voter fraud has happened in the past and no one has picked up on it? Yes. -- But I mean, we're talking VERY CLOSE races in districts were a few hundred or a few thousand votes could change the election. That's a logistical nightmare to pull off and the risks are immense to those involved.
Not sure many people would put their careers and their freedom (massive jail time for orchestrating this) on the line for this sort of thing.
Could it possibly be because they are already in control of those districts where it is most likely, and that certain policy positions, such as open borders are more conductive to voter fraud? Could it be that Republicans tend to have more respect for rule of law? Of course not, false equivalence to the rescue!
It is a well documented fact voter fraud happens, furthermore investigations into such activities were actively blocked by Democrat controlled states, making a complete investigation of the matter that much more difficult. It is not such a logistical nightmare if you know how the systems work, check out the documentary above titled "Hacking Democracy" produced by HBO where they go into detail exactly how it is pulled off and hidden.
There is not much of a risk if hardly anyone is prosecuted let alone caught now is there? Lets not forget as well that anyone of any moderate influence will maintain plausible deniability over the matter and insure they are insulated from the direct activities of voter fraud that can be proven.
