It’s true that he’s often unintentionally funny, and as a result, one tends to discount him. However, we shouldn’t forget that Biden himself is extremely left wing - he has the third most leftwing voting record in the Senate, IIRC.
He also, like his master, Obama, has a seriously spiteful and vindictive side. One of the reasons Obama made his big speech today and semi-retired from the campaign trail is that he doesn’t want to get caught in any last-minute moments where the mask slips and the real Red Barry’s fangs show through. That was what happened with Biden, and I bet they’ll pull him off all interviews now that this has become public.
It’s not because Barry is somewhat black, it’s because he’s more than a little Red.
Will be an interesting last few days, until the election, if the Dem Candidates, their wives, etc. go into hiding, such as they seem to be doing.
