Here's a remarkably constant factor to bear in mind in the debate over the federal health-care law: Most Americans say it hasn't really impacted them one way or the other.

A new Gallup poll out this week shows that 64 percent of Americans say the law has not affected them or their family, even as many of Obamacare's features have been implemented. Among those who say they have felt an impact, 19 percent say it has hurt them and their family, while 13 percent say it has helped.


What's clear is that ever since the core pieces of the law began to take effect late last year, Americans have been feeling the impact of the law a bit more. And the good news for President Obama and Democrats who voted for the measure is that the percentage saying it has helped them has ticked up slightly.

Still, the numbers have not moved that much. And they remain largely in line with where they've been since the spring of 2012. Overall, there's been virtually no movement since that time, even as more and more components of the law have kicked in.

Politically, the question moving forward is twofold and especially pertinent for Democrats, who have been put on defense by the law's rocky rollout: 1) Will the share of the public feeling the effects of the law increase dramatically between now and November? 2) If so, how will that affect the balance between those who feel they have been hurt and those who feel they have been helped?

With the health-care law emerging as a focal point in the midterm campaign, the answers to those two questions could speak volumes about the trajectory of the Obamacare debate as November draws near.
