The most recent poll shows health and economy are tied at 24 percent as voters’ No. 1 issue.

For the first time in at least 3 1/2 years, health care is tied with the economy as voters’ top issue, as news coverage of Republicans’ attempts to repeal the Affordable Care Act intensified in recent months.

Twenty-four percent of voters said health care is the No. 1 issue on their minds in casting votes for Senate or House elections, according to a new Morning Consult/POLITICO survey of 1,987 registered voters. In the Sept. 22-24 poll, the same percentage of voters said their top priority was the economy when determining votes for federal offices; that topic has been the No. 1 concern for a plurality of voters since Morning Consult started asking the question in March 2014.

At 22 percent, security, which typically ranks second after the economy, was the next most important issue among voters. The online poll has a margin of error of plus or minus 2 percentage points.

Voters’ interest in health care this month may be a result of widespread coverage of Senate Republicans’ latest attempt to unravel the ACA, which was subjected to stinging attacks from popular late-night host Jimmy Kimmel that reverberated on social media and on news channels. In the poll, 54 percent of voters said they’ve seen, read or heard at least some about Kimmel’s comments.
