Is the Biden campaign the most negative in history?

No. In 1828 John Quincey Adams actually accused Andrew Jackson of mass murder...oh, wait, Biden said what? Okay, never mind. 

All he can present is what he didn't do in his eight years in the White House!

No. It's quite positive.  Trump's has been the most negative and dividing, proving he's not qualified to be president of the United States 

I have been involved in negative campaigns.  Compared to most of them, the limited personal attacks by Biden on Trump are like a walk in the park.

Furthermore, a Trump supporter making this claim is like whining about the splinter in the other guy's eye while missing the plank in your own.  In both, presidential campaigns, Trump has falsely accused the other candidate of criminal activity, called them names, and threatened to imprison his opponents.

Even then the Trump campaign merely ranks in the top 1% of negative campaigns.  For comparison, look at the 1884 presidential campaign -- Blaine vs. Cleveland -- in which Blaine was referred to as the "continental liar from the state of Maine" and Cleveland was accused of having an illegitimate child.  

I don't see that.  Not sure why you ask.  It isn't negative to use the other person's actual work as proof of his lack of competence.  That is just pointing out reality.  Negative, for me, would be "Crooked Hillary, lock her up" and so on.  No truth, just negative accusations.  Once again, an obvious case of trumpite projection, claiming that the other one (the not-Trump competitor) is doing what Trump is actually doing.

It's the only one I remember where the candidate remains in hiding as much as he can.
