We don’t live under a parliamentary system. This is a winner take all republic. Proportion does not count. The Constitution institutionalizes the Electoral College. This “new majority” simply doesn’t matter, yet. And what do pampered white feminists and POC have in common? Little or nothing. Your proposed “majority” will splinter along self-interest lines in a minute.
I find Donald Trump disgusting. I find Identity Politics even more disgusting.
Also, I am one of those old, white males that you seem to despise. Odd, aren’t you? Self-loathing is a terrible thing.
