Can u tell me what is Donald Trump's biggest weakness right now ?

Pride, or lack of humility would be right up there in my book, but I think lack of self reflection probably is a bigger problem.

The Donald, as a bragging, lying pussy grabber, who tells it like it is, seems to be a pretty sellable commodity, but it seems like he starts believing his own bullshit too much sometimes, and doesn't modify his product enough for different markets.

Lying, bullying and joking in a rally with a room full of red hat wearing people saluting him got him elected, and he seems moderately capable of giving a decent scripted speech at times and toning down his rhetoric a bit, but it seems like he's still struggling with modifying his persona to carry it into different arenas.

He's much more suited to being a dictator, and I think he knows it, but he's going to continue to struggle with foreign leaders, the press, and other branches of government until he can step back and realize that some customers not only need different approaches, and that they'll remember being swindled in the past.
