Your candidate’s ‘process’ as he executes it is his downfall.
It may well turn out that way. But, I’m content to let the process run to completion. Changing the process that is in place is going to require real grass roots work, going to meetings, sacrifice of time and treasure.
But, before you go all in for full bore and unmitigated direct democracy...two words: Voter Fraud. We like to think that the Democrats have a monopoly on that. But, the lust to power is not exclusive to any ideology. It is a part of fallen humanity.
Like it or not, a study of the basis on which the Republic was established shows great alarms about the prospect of “tyranny of the majority.” For one example, that is why we have two bodies in the legislative branch, not one.
Returning to process (and laying side the specifics of the current sorry state of the GOP), a political party will also seek it own ongoing survival as a viable entity by internal checks and balances. And a dispersal of power is a reflection of (small r) republican principles.
If that dispersal is unsavory , then change the rules, state by state. But, it’s going to require a lot of work to assure that the majority wins it all every time.
And you may not like the way that ultimately works out.
