First of all, linking liberal with reasonable citizen is a stretch.  In your mind, maybe but certainly not mine. 

But to the crux of your argument, google "sane" and you will get "free from mental derangement; having a sound, healthy mind: a sane person. having or showing reason, sound judgment, or good sense: sane advice. sound; healthy."  Joe Biden does not meet that standard and thus you just made the case for Trump, no matter how many warts.
