Let's take a shot at Trump from the Trade Union Democrat position, because he did legitimately lose some of those in 2020.

Frankly, his leftwing economic policies of protectionism did benefit American labor. The trade war with China was rough, but it was more because of China than it was because of him, because China was already fucking American workers. (I remember a specific case where China cancelled something like 100 million tons of soybeans after it was already planted, and the US government basically had to bail out the farmers.) There were some people on the east-coast who didn't benefit much from the Trump tax cuts...

But that's about all I can say for the Union Dem positions. Contrast that to Biden literally cutting the throat of the Oil Workers Unions for blowing up the pipeline the day he took office! The war on cars, the war on petroleum, the complete lack of protectionism, while allowing international corporations to dominate the American manufacturing industries in order to make sure they don't have to deal with protectionist policies.

The only reason to vote for Biden is because it makes you feel good to vote for "the right guy"... who happens to be one of the single worst presidents in American history. Like, we're talking about James Buchanan levels of shit here. I seriously wonder if we'd be better off under Woodrow Wilson!
