I dont buy this. Mid term elections tend to get much smaller turnouts and are dominated more by extreme partisans than anything else. What I think the 2010 elections were was a referendum of exasperation with the length of the recession and so Republicans got a kick back of more seats. I think by 2010 no one was feeling any effects of Obamacare but positive ones and I think a slight majority of all people would have been in favor of the law. I dont think the 2010 elections had anything to do with Obamacare because if getting rid of Obamacare was so important, Obama would have lost in 2012.
Democrats made proposals that were necessary to get enough votes from democrats to pass the bill and nothing more. Slightly to the right of where most democrats want the bill is still well left of where most people wanted it to be.
Right now, polling seems to show that those who are ok with Obamacare plus those who want it to be expanded having been increasing to about half of those who have an opinion.
I'd suggest that thinking the bill is well to the left of where most people want it to be is probably as bad of a misreading of public opinion as thinking that Romney was going to smash Obama.
Romney was a pretty weak candidate, but the 2010 mid-term elections was something of a referendum on the health care debate. I'm not surprised that it's polling reasonably well at the moment since none of the warts are apparent yet. Sadly, by the time people realize the problems with it it will be too late to remedy them.
So most people blamed the republicans for the economy in 2008 and 2012 but not in 2010? I doubt it.
Just about everybody blamed the economy on the Republicans in 2008. Obama didn't win by a much larger margin because he was a black candidate and perceived as extremely liberal.
In 2010, I think most people were still blaming the economy on the Republicans but Republicans waged a better campaign to take back lost seats because they got the vote out better than the Democrats did. Dems just weren't inspired to go vote for a non-Presidential candidates in the mid-term. It doesn't mean most of America didn't still blame the Republicans, it just means Republicans did a better job of empowering their base to vote against the Democrats and used the economy not recovering fast enough as a weapon.
In 2012, I think people started realizing the economy was turning around, that it was only the Republicans claiming doom and gloom about the economy and so I think more people voted Democrat. They trusted the guy who was in office as things were getting better rather than the guy that was constantly lying, misrepresenting his positions, claiming things weren't getting better when people could see they were and insulting half the population.
I just don't see where either of the last two elections were a referendum on Obamacare. They were about the economy, the ability of parties to bring out the vote and the candidates involved, in the presidential elections as well as the Congressional elections(as evidenced by many 8 Tea Partiers losing after one term).
