The growing socialist movement with the Democrat party seems to belie that. Lemmings moving toward the cliff ...
This kind of language is why you have a hard time connecting with guys like myself on the left.
The real socialists don't like being associated with the neoliberal Democratic party, but they don't have a lot of options for representation.
The Democrats who are agreeable with social programs don't like being called socialists because, they aren't socialists.
Broadly categorizing Democrats as being single issue voters rings pretty hollow. The issue is not just Anti-Trump. Trump represents a great many things that bother all manner of left-leaning Americans albeit for different reasons.
As far as how this might effect guns, I get the feeling that a fair number of Democrats have begun to adopt more of a wait-and-see approach. Many of us have learned that gun regulation is an absolute loser and aren't really willing to engage in it, especially after the Heller and McDonald decisions.
In fact, one of the guys who called himself a Democratic Socialist; Bernie Sanders (who isn't really a socialist), has been historically tepid on supporting gun legislation. A fact that primary opponents were happy to use to beat him over the head. He tried to more closely align with the DNC platform for 2020, unsuccessfully so.
It's something of a difficult time for the Democratic Party even though they look to be on the cusp of a pretty substantial win in a couple weeks. Support for gun legislation is low, even among actual Democratic politicians and their constituents, despite still being a part of the DNC platform with the usual assault weapons legislation, universal background checks, ending online sales, etc. It's one of the reasons I sought out and joined the Socialist Rifle Association, because I believe the Democrats approach to gun control is wrong and causes more harm than good. It only takes a quick look at statistics on poverty and the war on drugs to realize that gun laws aren't effective in reducing crime.
