Let me come up with some analogy so that my point can be better illustrated. Say, I have no car and need to borrrow one for a week from my mate. I have no other option - must borrow one from him and not from anybody else. He offers me one of two $hitty old cars available. The 'A' model has steering problems - every now and then the car can veer off by 1 meter either left or right while driving. The 'B' model has a solid steering but its brakes are dodgy - breaking distance is much longer.
Now, which one do I pick? I don't like any of them but have to pick one. Which one is more likely to get me into trouble? Over which one can I have more control?
Clearly 'A' is far too risky - what if it veers off 1 meter to my right while passing oncoming traffic ? That would be pretty much be the end for me.
The one with the faulty breaks can get me in trouble too, but if I keep more distance between other vehicles, I'd have more chances (=less liablity) of getting myself into trouble. Still there is a chance but better this than loose steering.
So, for me the 'A' car represents Biden, 'B' is Trump.
