I know but I think it's in his nature. Both as a narcissist who will be in depression and as an America-hating neo-Colonialist. It will be in keeping with being the most disrespectful president in history. Something he might see as a plus for his future standing as a post-American ex-president.
I suppose MO would threaten to beat his twerpy little butt though if he tried it. She has her post WH status to think about too.
Oh, I'm sure his inner thug would just love to diss Romney and Ryan by not showing up to their inauguration, but even Barky knows that he'd be branded as a hateful little loser for life, if he did it.
I'd more expect for him to show up and try to steal the limelight, in a grand preparation for his next job as Emperor of The World .. LOL
(You're right. Mooch would twist his ears off if he missed it)
