I have proven that it in my initial response.
The Democrats can not win on policy for the foreseeable future so you want to change the rules by which all elections have occurred in our country.
Would the Dems be gerrymandering if they had power, would the Dems change the rules of the Senate when they have power? Of course they would. The Dems simple do not have good candidates nor policys nor results despite the fact they tried rig the last election. The Dems had the media and the deep state and entrenched partisan bureaucrats and they still could not win. The Democrats have failed at all levels and they know it, and that is why they need to cheat lie and try to change the rules to rig the system.
Then you don't know what a proof is. You failed to supply a shred of evidence. Evidence on Republican corruption can be found in massive quantities.
Let's cut to the chase, shall we?
Prof Tribe got it right, what we have is minority rule. That's kinda the opposite of democracy.
Btw, if you look at polls, Americans, in some polls even Republicans, favor policies that Dems want.
And while you say Dems can't win, we had a Blue Wave in the last election, despite Republican cheating.
Which is why they are cheating even harder now.
