People who work declining agriculture and heavy industry jobs want easy solutions. Republicans promise them easy solutions (tarrifs, bring the jobs back, stop immigration). Democrats bring up difficult things (retraining, actually nothing else).
So of course they want the easy solution. Who wouldn’t (doesn’t matter if it will work or not, the hard one sounds too hard for them).
Dems need to find easy solutions to get those people on board, otherwise they are screwed. Biden has started doing this by embracing tariffs on China (which are not working, but are VERY popular among the people they are slightly hurting).
