You're pretty much right. There is, however, a problem. The Dems just don't want to upset the GOP by saying that kind of stuff. Last night I was watching Lindsey Graham talk about how Trump would have put Putin in his place over messing with our major company's software hacks. Then somebody else pointed out how poorly he did with Putin when he had a chance - basically he said Russia just wouldn't do that because he said so.
This is the kind of stuff that needs to be fed to the GOP base every hour or so. Just hammer it into their thick heads! Oh, I know, the kindly Dems wouldn't do anything like that. That would be just pure mean and they are terribly concerned about that? The Dems should create a book of GOP lies, all of them, and then distribute that to their Dem candidates - just for starters. I know, not gonna happen!
