  • Round 2 on the Legal Challenges to Contraceptive Coverage: Are Nonprofits “Substantially Burdened” by the “Accommodation”?

    Issue Brief

Issues specific to the ACA, such as repealing provisions of the law or repealing the law entirely, fall much lower on the list. The survey also probes the public's experiences with drug advertisements. A large majority (82%) report they’ve seen or heard such advertising, and 28 percent say they have talked with a doctor about a specific drug they saw advertised. Favorable and unfavorable views of the health care law are tied this month with 42 percent favorable and 42 percent unfavorable.
