But, I don't think this was a repudiation of Obama. Obama's approval rating is over 55%, much higher than either of the candidates. Obamacare has some issues, especially in regard to the rate hikes we're about to see. But, I don't think this election is the result of repudiating the policies of a president that most of the country approves of.
I do believe this was a total repudiation of Obama and his policies. His approval rating was 42% for most of the past 3 years and only spiked during this election because both candidates were so horrible. I do believe history will show Obama as our worst president ever - but he'll always be a hero to the African community because he was the first to reach the Presidency so for that alone his numbers will be higher. Here's some examples on what people are rejecting:
1) all of the illegal executive orders he signed.
2) wanting amnesty and no security of our border.
3) praising BlackLivesMatter in speeches even though they parade around calling for police to be killed.
4) refusing to say the words 'Islamic terrorism'
5) Affordable Care Act - it doesn't work and will implode on its own. But Trump can expedite it.
6) Supreme Court - we don't more activist judges legislating their agenda from the bench. Trump will be a conservative and put a conservative on the bench - we need another Sam Alito
7) Bringing Syrian refuges to the United States. I'm okay helping them but provide the assistance in their own country. We cannot just resettle everyone in America on the taxpayer dime
National Anthem handling - people are infuriated about folks kneeling for the national anthem. And Obama sympathizing with them just shows his support for it. Time to treat our flag and country with respect - stand!
Transgender movement - Obama dictating that schools must adhere to his bathroom guidelines of have their funding pulled is ridiculous.
I disagree with most of your list, but I get that there are multiple reasonable ways to look at it. I think you actually missed a couple of criticisms.
1. While the economy has stabilized, it hasn't grown very fast under him. Part of that is that it needed to stabilize before growing, but we should be growing more quickly than we are. That's starting to change (salary increases are growing faster today than earlier in his presidency), but it has been slow.
2. The country is more divided today than 8 years ago. That's not all on him, but that's a major failure of any presidency.
But, while I bet that his approval rating has improved as a result of the election, I'm not sure that's all of it. Part of this is a function of disagreeing with most of your list, but I approve of the job Obama is doing. And while there are valid criticisms of him, there are also a lot of reasons people like him other than not being Trump/Hillary.
