Democrats cite healthcare as the top issue for the 2018 midterm elections, according to a new poll. But high costs, not Obamacare, is the major issue concerning voters.

The poll released Thursday by the research firm Kaiser Family Foundation showed that 30 percent of Democrats rank healthcare as the top issue, with 19 percent of independents ranking it No. 1, second behind the economy and jobs at 22 percent. For Republicans, 15 percent list healthcare as the top issue, fourth behind the economy, immigration, and gun policy.
