Can you point to any mainstream democrat who made accusations that voters were changed or forged in 2016? Democrats were claiming the process was compromised. I don't remember anyone seriously questioning the integrity of the votes themselves.
The claims weren't just that the system was compromised, but also that votes were manipulated or suppressed.
Harry Reid made claims that the vote totals were manipulated.
On a side note... thank you. At least you asked a question about my position rather than simply downvoting without an explanation.
Mea culpa, I was wrong to say "no mainstream democrat", but that was a single retired congressperson. The Republicans now also have two members of Congress who believe that Democrats participate in ritual sacrifice of children to drink their blood so maybe we shouldn't focus on the extreme minority opinions of these parties. Voter fraud is a rallying cry of a large percentage of the Republican party. Votes being changed in 2016 or any other election is not a major rallying cry of a large percentage of the Democratic party.
I believe he was an active US senator at the time (2015-2016). I forget if he was majority leader or minority whip, it if that was during a different part of his tenure.
I do agree that it seemed somewhat isolated in official statements. I did hear quite a few individuals in my personal life believe/state that since the system was compromised that must mean the votes/count must have been changed.
I can see how the fraud claim is popular - if you're losing the popular vote consistently due to (simplistically) higher urban population, you might look for something to use as an excuse. This makes an easy excuse since in your constituent areas (rural) you would have the observation bias that almost everyone you know voted for your candidate and still lost. Sloppy voting system maintenance supplies plenty of anecdotal things to point to, like dead people kn the voting role.
