That all is true... that he’s quite successful in the business world... but the world of governance is a whole different animal. IF he gets there.. and that’s a big IF...he will find he can’t summarily fire people who don’t do his bidding on demand. I’m not convinced he understands the constitutional co-equal status of the three branches of government.
I think that he understands it - or that he’ll be made to understand it by his advisers and allies.
Of course, Obama has largely ignored the other 2 branches...but I’d really love to have him be the last President who does so.
