The right, in general, is not nearly as popular as it was when I was a kid. The current movement was started because they were losing ground in a way that was not recoverable. The minority has been orchestrating a take over for decades because they realize that their long term prospects are dire. This is an animal backed into a corner, fighting for it's life, and it is already seeing a massive, and growing backlash. The GOP is literally going bankrupt. This is despite stacking the courts, and other footholds they spent decades creating.

As for current incremental progressive causes I personally work on?

Changing the style of voting in my state from FTPT. It has already taken a couple states, and is growing in popularity across the country.
Reduction of drug draconian drug laws. Weed is very much on it's way to a federal legalization. More, and more, places have been working with decriminalization of hard drugs. I used to work in data analysis in the "corrections" system and it is definitely moving away from simply punishing non-violent criminals. Most municipalities now move people committing crimes for addiction into rehab, have been increasing the number of ways they will keep charges off your record for long term compliance with rehab, and sober living. There is also a growing movement towards these things outside of just addiction. The momentum is towards rehabilitation for most non-violent crimes. Healthcare reform. This one is more of a sleeper to those not working within organizations working towards it. When I became and adult there was literally no way for me to get any form of health coverage, at all, full stop. Now I can not only get coverage, it doesn't require things like a 25k deductible. Pricing cap legislation is being pushed, other price regulation for drugs is being pushed, and, despite it being one of the top three most heavily lobbied industries. The amount of the general public, and medical professionals, who support socialized healthcare has been growing.

As for the things I don't donate time time to work on, personally. The position minority communities are in is better than when I was a kid, even with recent regressive gains in some places, taken into consideration. These regressive movements are already under strong fire, and, even in deep red states, are not going to last. Even the courts they stacked are backing off on their support of the movement, because it is proving to be unpopular to the point they are being forced to choose the viability of their career, in the long term, over current clout that will likely not manifest the gains promised. This is combined with the USSC, and some other fed judges, having issues come to light that are sidetracking most of what they do, in order to just claw onto their position. Labor organization is the most popular it has been since the 40s. Labor organization has been making the biggest gains, both in terms of unionization of workers, and in the legal theater, since my father was born. The most popular candidate of the right is an absolute shit-show, and other than his minority-in-a-minority, cult of personality, is driving people away, and stressing the foundations of the party. Meanwhile the DNC is slowly deciding to pull it's head, at least somewhat, out of it's ass, and has dumped joe for the most progressive primary candidate we have had in a long time. She is also the first to hold that position, for a number of categories. Is she a leftist? No, not even close, I didn't even expect that as a possibility, however she is a step further left than what we have seen get the position of primary candidate. We actually, finally, have serious work towards judicial reform. Government immunity is also finally in the crosshairs of the majority of democrats.

I could go on. Compared to 40 years ago, a LOT of progressive legislation has happened, and the ones that saw the biggest attacks from the neo-liberals are, again, seeing massive resurgences in popularity. Even when you look at the youth that has decided to support right wing parties, when you ask them what they think think is needed to better their position in life, it is largely progressive desires, even though they don't seem to understand that. Every time I read surveys of that population, the vast majority of their issues are loss of workers rights, too much corporate control, not enough regulation against dangerous business practices, need for legal mandates to make more housing, and to keep artificial inflation down, unaffordable healthcare, the weakening of public education, especially in terms of the costs of university, wealth disparity, etc.

All of this is better than living under a dictatorship, you know, like a "democracy" that has one candidate, that gets appointed for life, and controls a police state, the likes of which Stalin couldn't have imagined.
