I think a lot of the hatred towards President Obama is, unfortunately, based on race.
The Affordable Care Act is a good example. As has been stated previously, this was originally a Republican plan designed by the right-wing Heritage Foundation back in the 90's. Obamacare kept all the for-profit insurance companies, did not include a public insurance program like Medicare for all, required people to buy insurance, and still left a bunch of people without care.
It was the exact same plan that Gov. Romney implemented in MA and was the plan the Repubs. proposed as the "sensible" capitalist alternative to "socialist Hillarycare". Obamacare was Bob Dole's Republican health care plan.
Better than nothing, but hardly what a socialist would design. Nowhere near as comprehensive as even the least generous health programs in other countries, like Canada and England. Every other country besides the US has non-profit, public health care available to all, not just to the elderly (Medicare) and poor (Medicaid).
So why did people go batsh!t crazy when offered Bob Dole's Romneycare program? Why did they act like it was the end of the world, and would destroy America? Why hadn't they acted like that when Bob Dole proposed it? Because it was being promoted by the black guy. I can't see any other reason.
It is even more telling that when people are offered the components of the ACA, not telling them that it is Obama's program, they overwhelmingly like it. Some 80% of people approve of the ACA when it is explained piece by piece.
I am formulating what I call the Mockingbird Theory of Racism. It is based on the story To Kill a Mockingbird. In that story, a black man was convicted of a rape he could not possibly have committed and died in prison. People focus on that aspect of the story. But I think the more insidious part of the tale was why the white community hated this black man so much. It was because he had helped a poor white girl and had pointed out that she had needed his help.
For a certain segment of the white population, low income, rural, low educated, the only thing that keeps their self-esteem above rock bottom is racism. At least they aren't black. Psychologically, all black people have to be below them. So, if a black person is in a position to help them, they have to reject it, even though it seems incredibly stupid. And wealthy, powerful whites love to use this racial stuff to keep people voting against themselves. Muslim! Socialist!
Obamacare is exactly that-- a black person offering to help them. They have to kill the mockingbird.
