Just as a question mostly because I'm not American.

Wasn't Biden leading the polls for the Democrats? Isn't it odd how much anti-Biden material online is rubbing off in similar fashion to anti-Bernie and then anti-Clinton material? Would this in any way be propaganda, or a way to diminish the leading Democratic person running? I know Biden has been saying and doing many things that aren't very appreciated, but I am curious to know if this is an intentional driven plot to diminish his current popularity. I know I saw questionable material on Yahoo before and it seems buzzwordy in a way to piss people off by using AOC.

I'm serious with my question and even if I am wrong I'd prefer answers than just disagreeing with my speculation that could be wrong. It's just that I have seen a lot of anti-Biden stuff that seems reflective off of what I saw in the past that lead to Trump's win.
