VP Debate: Pence v. Kaine

Hello beloved readers. It's been quite a while, but I have a quick one here as I watch the VP Debate:

• Kaine interrupting WAY too much
• Both guys talking over one another a bit too much, but mostly due to bullet #1; and finally
• Agree with his positions or not, why isn't PENCE the Presidential candidate?!? He's head and shoulders (and torso and legs) above the his Presidential-candidate running mate-- i.e. he can calmly and measuredly string together a sentence composed of more than 3 words-- none of which are superlatives-- without mentioning Rosie O'Donnell or going down a rabbit hole
