Sure, and you know I know the rigging is the problem but Democrats don't seem capable of fixing it, while the GOP is plenty capable of and successfully making it worse. I don't see Democrats maintaining control in 2022 without at least one huge domestic accomplishment that Americans actually feel before the election.
It's not fixable because it's ingrained in the Constitution. Not only does the Senate give the less populous states extra representation, the Electoral College goes even further and uses this unequal representation to pick the highest office in the land. But since the GOP can barely win a rigged game fairly, they go way beyond that with outright voter suppression layered on gerrymandering. And now because a Supreme Court justice was stolen by Moscow Mitch, we're likely to lose the SC for a generation.
The only solution for Democrats is to run up big enough scores that the GOP can't win the presidency anytime soon. I realize California isn't a model for the country, but the GOP is completely irrelevant at the statewide level. Although that doesn't fix the unfairness of the Senate, or undo gerrymandering, or undo voter suppression, POTUS is at least a bulwark against a Republican-controlled Senate. The party of the President likely controls the House, so all the GOP can do then is run obstruction in the Senate.
I suppose you can kind of fix the Electoral College problem if the National Popular Vote Interstate Compact becomes in force. The Supreme Court could return to its previous status quo if two left-of-center justices were added. I don't believe that is under serious consideration with the bare congressional advantage Democrats currently hold.
It's hard to predict the future, but long-term, the GQP brand looks dismal. Recent events have made me less optimistic about the future because not all insurrectionists were old folks. But the writing is kind of on the wall w.r.t demographic changes (see 2020 Census). Georgia will become a lean blue state, and Texas will ultimately do the same. If the GQP doesn't rebrand itself, their pathways to the White House will become extremely limited down the road. The problems for us all is that can still be decades away, and Jan. 6th laid the groundwork for the end of our democratic experiment.
