Harris is simply not smart enough to stand up to Trump over time. She will stumble, and yes, there is enough time for that.
Trump has to learn to keep his big mouth shut. He needs to let her implode, just like Biden did in their debate. When he debates her, it will be more important for him to be quiet than it was against Biden. He will get labelled a racist if he battles her.

This may turn out to be the genius of this process.
There may not be enough time to expose her.
I, frankly, don't care at this point.
What I have learned is that D.C. is corrupt and they see us as idiots.
