Americans became much more concerned about healthcare this month, with 18% naming it as the most important problem facing the U.S. Mentions of healthcare tie with mentions of “dissatisfaction with government/poor leadership” at the top of the most important problems list. This is the highest percentage mentioning healthcare since November 2013, amid the troubled rollout of the government healthcare exchanges.

These results are based on a Gallup poll conducted May 3-7, in the midst of the House vote on the American Health Care Act, the replacement bill for the Affordable Care Act. That vote followed a failed effort in the House in March to bring the original version of the bill to a vote. The Senate will now act on the healthcare legislation.
