I think the issue is that, as @Hank Kingsley has pointed out, this isn’t a strategy. In the first instance, there aren’t enough poor and blue collar Americans to win national elections.
Second, even if they were, the issues are different. Why are you poor? Were you born into generational poverty and shitty schools and never had a chance? Were you middle class and then the factory in town moved to China? Did you graduate with a CS degree and now no one is hiring?
Trump appeals to parts of the poor and blue collar all the time, that’s what the tariffs and bringing back manufacturing schtick is all about. You can (accurately) say it’s all BS and hypocrisy and a sham but you can’t say he’s ignoring that sector and their issues. He’s all about them and it was likely key to the win.
If step one of your plan is “create a class consciousness in America” then it’s time to ask if the plan is really to win an election. Otherwise, the question is HOW are you going to appeal to the working class.
