He was not. He was the most successful president in generations. He got nearly everything he wanted. He weakened our military, ruined relations with our allies, made us weak in the eyes of our enemies, thereby emboldening him. He wreaked havoc in banking and finance, brought the economy to it's knees and kept it there for 8 years. He damn near destroyed the health insurance industry for consumers. He set race relations back by 50 years. After 8 years of his presidency this country is more divided than ant any time in the last 150 years. Old vs young, white vs black, black vs everyone else, male vs female. He made Christianity a hated religion among many. He made his moronic minions see traditional Americans as intolerant bigots. He made white males the 'enemy' who must be destroyed.
All part of his agenda. He was very, very successful.
It is easy to destroy things. However, Trump will eliminate 0bama's legacy in less than a year.
NOTHING will survive. 0bama is an incompetent boob.
