Thinking about one of the biggest debates of the last few years, I am confident that Obama and the Dems really believe they would have significant republican support for the Affordable Care Act (not trying to start a HC debate) since they pulled the plan directly from the Heritage Foundation. I think they were genuinely surprised there was zero support and engagement for what was previously acknowledge as the best capitalist version of universal healthcare. And sadly, if the plan had not had to have been cobbled together with only Dem votes (and their corresponding special interests) the final bill may have been pretty good.
We have heard Republicans say out loud that they decided to be against things just because Obama was for them.
I know these things can go both ways, but I think that one side is more blatantly oppositional than the other.
Having been an R for 20 years and an I and D for 10, I feel like I get the ideologies of all of them, and I was actually turned away from the R's because I not participate in the hypocrisy of the Clinton witch hunt, even tough I voted against him twice.
I have come to believe that people interested In Finding common ground have mostly given up.
