She was in primaries some time ago and gain less than 10% votes.
I said, if the Democrats have chosen someone more charismatic than Harris, they would have won.
Well.. Trump was elected. If you're not saying Trump is more charismatic then this all seems to contradict your point that charisma is necessary for electibility.
You are making a logical jump there. Hillary and Harris are Democrats. Trump is Republican. Based on logic, just because Trump won doesn't automatically make him more charismatic, as there are other factors that play role.
So logically you cannot assert that this is true; Trump winning <==> Trump more charismatic
Republicans don't need charisma: if the Democratic candidate isn't charismatic enough, they'll instead vote for whatever pile of shit the GOP puts on the ticket.
The problem is the voters.
But saying Trump was more charismatic than Harris, your cat, or the shit I took this morning is certainly a divisive opinion at least.
I've encountered farts which cleared a room and were still more "charismatic" than Trump according to 9 out of 10 people exposed to both.
