Anyone seen this (link) or on their list? IMO, the republicans are going to have to give up being clever and simply learn to cheat with the same effectiveness as democrats if they want an even playing field. https://bankyourvote.com/
Can you imagine what the media would do if there were any proof (legitimate or otherwise) if Republicans cheated? No winning Republicans would ever be held up as being legitimate. Then there's the whole "If I behave as my enemy, I am defeated" thing.
I don't know about cheating, but I understand Republicans are now doing ballot harvesting where it is legal, just as the Democrats have done for a while. As far as I know, the Republicans don't bus voters to several states to vote as the Dems have been doing for at least a decade or more.
I think I read about the ballot harvesting also. It seems to me republicans think status quo is some sort of defense. They can be a frustrating group with their seeming complacency.
