How did Obama treat conservatives like dirt? The ACA was originally a Republican plan, unfortunately Obama couldn't get anything but a shitty version of it passed, and even then conservatives have been trying to get rid of it ever since. Then there is expanded Medicaid, which costs the states nothing but a number thumbed their nose at simply because it was Obama's idea. And I can't think of anything else he was able to accomplish.

I've never seen the two parties fail to compromise as they did during his administration. Some have suggested it's because Obama is black. And largely I believe racism is a red herring, but I don't know another reason for it.
