MUCH of what you are advocating gets stymied partially because how Liberals talk to the rest of the country and also, how Liberals have their own version of Taliban orthodoxy on certain social issues.

I think it mostly gets stymied by the right-wing, and their dogmatic campaign promises (e.g. "tax cuts"). Sure, the left has a problem with framing issues. The right is big on "one-liners". To explain nuance generally can't be done in one line, and the world is full of nuance these days. Maybe it always was, but it's extremely evident today. So, yeah...Dems have a difficult time with messaging.

I think there is far more "Taliban" among the right. Both extremes -left and right- have their authoritarians. It seems to me that the right has a narrower band of moderates in their spectrum, so a wider band of authoritarians. It was the straw that broke the camel's back for me. My party (the GOP) was on the one hand saying "government stay out of our lives", and then the other hand "live how we dictate based on ancient fables". Hypocrites. So I left (no pun intended).

I don't agree with everything the left does. Far from it. I have numerous complaints about Obama (arguably the best POTUS we've had in over a century). I find the left is less wrong than the right, especially the MAGA right. The MAGA right gets almost nothing correct. So I mostly vote for Dems these days, unless there is something really wrong with the Dem in question (e.g. if I lived in the correct district, I would NOT have voted for Menendez; nor Robert Byrd; etc).
