Opinions about Obamacare are holding steady:

Blumenthal investigates:
The most likely reason general attitudes about the law have not changed is that so few Americans have sense of how the law will affect them. "Two years after passage," the Kaiser analysts write, "the ACA is not yet 'real' for most Americans — six in ten say they don't have enough information to understand how the law will impact them, and two thirds say the law has not yet affected their family in either a positive or negative way."
Unless and until that experience changes, attitudes toward the health care reform law are unlikely to shift in a meaningful way.
And the responsibility for this lies with the Obama administration who have shown no talent, zest or intelligence in explaining and selling their core domestic achievement.
