Writing at Hot Air, David Strom provides a useful distinction between a “stolen” election and one that was “rigged.”
A “rigged” election is not the same thing as a stolen election; stealing requires changing votes. “Rigging” is about changing the rules, the information landscape, or other factors that can influence voters using illegitimate means. Spreading misinformation can be a form of rigging, as of course censorship or “debunking” of true information.
I couldn’t say if the 2020 election was stolen–there certainly were irregularities as there always are in elections–because any vote changes or illegal ballots have to be in the right place in the right numbers, and no evidence has been accepted by courts indicating that enough illegal votes to change the results were cast.
But certainly, the election was rigged. Lots of illegal changes to election laws were made without legislative approval, Big Tech censored conservatives based on phony claims, and the media colluded with outside groups to distort the truth or deny facts.
The main stream media all supports one of our two major parties, and has done so for a couple of decades. You could argue that the last several presidential elections have been rigged - some successfully, some not enough.
