Since you seem to be all about the conspiracies, let’s try this on for size. Shut down ALL electronic voting. Mandate everyone in every state show a valid form of ID to ensure only valid citizens are casting votes. Then declare that you want all votes counted in public. In the Town Square. Twice.
What do you mean by all electronic voting? In my city, we fill out paper forms which are scanned by a machine. It's already illegal for non-citizens to vote, and people already have to show valid ID in most places to vote (I did), but those IDs don't prove citizenship -- not even a Real ID (except, optionally, in a handful of states). Not everyone has a passport or access to their birth certificate, and getting them costs money. Also many places provide viewing of the ballot counting and all places allow observers from the political parties and media -- a Town Square isn't a secure area for vote counting.
When America finds only ONE political party bitching endlessly about these “unfair” demands, you will then KNOW who the fuck has been cheating.
For decades.
Democrats complain because most efforts by Republicans are unfair or onerous to at least some people, usually poor(er) people who don't usually vote for Republicans. As far as cheating... Republicans are the ones gerrymandering states to squeeze out democrats, trying to get the federal Post Office to manage state mail ballots, threatening to send ICE and/or military to polling places (which is illegal), talking about nationalizing elections, which is contrary to the Constitution. Republicans have nothing to run on to entice voters, so they have to resort to tricks to stay in power.
