I agree with your premise (today men are often ignored or meeting many issues), but not with your solution: Trump is a narcissist psychopath (most therapists would agree) so he just cares about himself.
All his promises are just empty words to gain approval and votes. It's not about Republicans or Democrats: it's about character, and Trump has that of a con-man.
Just because the political Left has, for a long time, ignored men’s needs to focus on women’s issues, it doesn’t mean the Right has the answer — especially the populist Right or tyrants like Trump.
