yes, they did fraud, see https://www.fraudspotters.com/statistics-about-dominion-election-fraud/ I personally verified all the stats in this for the owner of the website.
Basically, counties that have dominion have a statistically significant 2% increase in voter share for democrats since dominion was instated compared to counties without dominion. This persists even after controlling for relevant factors (voting trends before dominion instated, prior voting patterns, demographics, etc.)
seeing that I am in college and have 2 jobs, I am super busy, but pretty soon I will make my own analysis similar to this and publish it. The chances of all of this happening randomly are about 1 in 10,000, after randomly simulating putting dominion in random states.
its really crazy that this stuff is true. but it is
I am kind of just waiting to see what happens in 2024. if they do it again, then the chances of it happening randomly will probably go from 1 in 10,000 to 1 in (10,000^2) or 1 in 100 million, which is a lot more interesting.
