I was paying attention back in 2008. As soon as Obama became a valid contender for Potus, the economy started tanking. He didn’t inherit a bad economy, he caused it to start tanking. Likewise, since Trump has become a viable contender for Potus, the economy started improving and that improvement accelerated dramatically when he won the election.
Business picked back up for us about 2012. BO had a re-election to win. It decreased again in 2014. Last December it fell to levels worse than 2009. My personal theory was that after the 2014 mid terms were behind the Pharoah, his attitude was a combination of who cares, scorched earth, and punishment to the middle class people of this country. He had a phone and a pen.
Just a personal perspective from someone highly impacted by the economic policies, or lack there of, of this administration.
