You are entitled to your suspicions. As I indicated, it is not impossible, I just think it unlikely.
Sounds like you've jumped to a conclusion unsupported by any facts.
A wise person withholds their opinion until they can state it beyond the level of "unlikely."
I can just as easily say it's unlikely that Harris would reject the offer to cheat given her debate performance of the past. Also it's a given that in 2016, the DNC co-chair, Donna Brazile, cheated by sending advance copies of CNN-sponsored candidate events to her friends working on the Hillary Clinton campaign.
So, is it really unlikely a Democrat would once again cheat given their history and the current "win at all costs" attitude of the Democrats?
I'm not jumping to a conclusion. I'm basing mine on experience and probabilities. You seem to be straddling the fence and refusing to look at anything that doesn't rise to the level of direct, incontrovertible evidence.
Don't be ashamed if you can't yet form an opinion either way. You have set an extremely high a bar for yourself. But holding others to that standard doesn't do anything to promote discussion. It's just argumentative.
Maybe you should wait to post your actual opinion instead of constantly shooting others' opinions down with words like "unlikely" -- an comment unsupported by any real evidence. It just makes you sound desperate for attention.
