Since its inception, Obamacare has been opposed by about a 3 to 2 margin. Those numbers have held relatively steady through two election cycles, cycles that have brought extreme fortunes to both major political parties. Never has a policy so detested by so many been promoted for so long. The Democrats' commitment to rule against the will of the people cannot be under emphasized.
We should also mention that support for Obamacare has rarely risen above 40%. It has never hit a majority for likely voters.
About 10% are either unaware of or apathetic about Obamacare. If that group were added to the minority, they would still be a minority. As the ACA takes its baby steps it is highly unlikely that the uninformed will embrace Pelosi's dream.
There is a story bigger than Obamacare and that is the growth of elitist authoritarianism (and authoritarian elitism.) The idea that the will of the people just does not matter has never been stronger. The age old saga of who and whom was less prominent in America than in places like Iran, Saudi Arabia and Cuba. The will of the people used to be a consideration. Who knows if it will ever again be relevant?
