Can you provide some examples? Because these are two I've seen floated around CF:
Harris occasionally stumbled over words, talked in circles during key events throughout the year.

and those two videos do not advance your case
at all. A few of the examples are needlessly wordy, but none of them were difficult to parse.
I'm not in the tank for her at all. I don't find her particularly engaging as a candidate; I'm skeptical of her executive/administrative skills; I've seen little of note from her tenure as VP; and I'm not convinced she can win. My vote for her is still a vote for !Trump and !Republicans.
What I am "in the tank for" is people approaching these issues as reasonable, intelligent adults, disregarding simple-minded propaganda from whatever direction it may come. If somebody can watch either of those two videos I posted and come away with the idea that she's speaking gobbledygook, then that person has either poor English skills, is highly susceptible to propaganda, or both.
