I hate to be a pessimist, I'm not sure I can agree for the left in this country. I can't think of a single state that is turning red(ish). States that turn are going purple or blue. Biden is going to be our President, with many thanks for that going to big tech and the MSM.
"Normal progressives" that get sick of over the top leftist rule (e.g., Calif and NY) either just complain, or on the state level, move, and too often take their "moderate" leftists ideas to their new states and start turning them purple. They may not like mandatory gender neutral bathrooms, but gosh, who needs those evil black rifles?
There are far too many people addicted to government handouts and free stuff. The very far left (e.g., antifa, BLM) will simply burn stuff down if they don't get their way, whether an R or D is in charge. The only way to stop the latter is with defensive violence. I'm not sure we, as a society, have the backbone for it.
Without picking up rifles, I think the best we can do is slow the flow. If the Electoral College goes, we're gone. Even with the Electoral College, as long as leftists get to be locusts, screwing up their cities and states and then moving to a "better state" to just be slightly less lefty (vote for gun control but not support CHOPs; not support free heroin for street addicts, but support uncontrolled immigration and voting for non-citizens), things will continue to go purple and blue.
Leftists are locusts who believe they know better than you and me. We could say the same about conservatives and libertarians, except that we also believe in "keep your nose out of my business, and I'll keep my nose out of yours." Progressives, on the other hand...
