I agree that a Trump presidency could be very bad. It looks like we disagree that it could also be good. I can see why you would see things that way, though. I can especially see it if you are getting all or most of your info from sources like NBC and NYT. They are purposely slanting the story. That said, Trump makes it easy for his haters to vilify him at times. He says and does things that I wish he wouldn't.
And regarding Bush vs. Obama, we were clearly in a very bad place at the end of Bush's term. Back in the Clinton years I was in the mortgage business. I absolutely hated the rules that were passed that loosened up lending. I told people that this was going to end in crisis because we were being forced to lend money to people who weren't going to be able to pay. Everyone said that it didn't matter because the government was backing them, but I knew that it would matter for both the homeowners and the taxpayers. I left the mortgage business because I couldn't live with what we were doing, and I was eventually even interviewed on PBS about my opinions.
I was not even a little bit surprised when it all blew up. Bush, who was already unpopular for his bad decision to go to war in Iraq, did a very hard thing. He pushed through legislation that increased his unpopularity in order to avert disaster. He should have dealt with the situation a lot earlier because there were a lot of people who knew this bubble eventually had to burst, but at least he did something when it absolutely had to be done. His actions solved the problem.
Obama stayed the course on Bush recovery plans and that was good. Obama also implemented big government programs and that is bad. Health care in particular, I vehemently disagree with. The core problems in healthcare have been worsened by Obamacare. Clearly we need reform, but every step he has taken in the name of reform has been in the wrong direction. We need less insurance company involvement, not more. We need less government intrusion, not more. What we really need to do is somehow get control of the legal aspect of healthcare (and other sectors of our society). We are allowing our own legal system to eat us alive. This is what's really causing healthcare costs to spiral out of control.
I have other issues with Obama as well. I do not think he's been a good president. I voted for him in '08 but have been extremely disappointed. Liberals aren't likely to acknowledge it, but the Obama presidency is the real reason that both parties are in such chaos in this election cycle. A large percentage of Americans are completely fed up with the way things are going.
