The last thing the USA needs – or indeed, the world needs - is another left-wing, 'progressive' (ie. quasi-totalitarian), social justice warrior in office. Unfortunately she's just another Hillary Clinton in waiting – without (I would hope) all the attendant highly illegal and completely immoral baggage. The wife of a former ineffectual, neo-liberal, social justice warrior, who has lived high on the hog for the best part of a decade and who now has got the taste for champaign socialism and wants more of it. God (!) help us.
Mr Obama was a disaster both domestically and internationally and I suspect that Mrs Obama is just more of the same. I wonder if she can speak coherently and articulately without the aid of an auto-cue? Her husband certainly couldn't. He was hopeless. A mumbling, stumbling, shambolic speaker if ever I heard one.
I've said it many times on this site: I think Trump is a buffoon and a dangerous one at that. But the idea that Mrs Obama is somehow a panacea to Trump is utterly delusional. The USA and the world needs a better class of leader.
My vote: Trey Gowdy.
