That's not definitive, to be sure. But it's sufficient for me to believe that we did this to ourselves. Now all we can do is figure out how we're going to get through it.
Yes, it might only take a small number of votes in the right place, but either you somehow know the right place, or you have to move a lot of votes.
There's a reasonable discussion to be had along the lines of 'these guys seem to be doing everything they whine about', but could they get a big operation done without a) bragging openly about it, b) leaving a big trail, or c) having a falling out with a conspirator who then tells all.
Adding on, certainly gerrymandering and voter supression laws affect voting results, but I have trouble calling that stealing an election.

If nothing else, that establishes a willingness to tamper with elections.
