In an expansive look at the 2018 midterm elections, this month's KFF Health Tracking Poll includes an in-depth examination of the role health care may be playing in midterm elections nationally, as well as in Florida and Nevada, two bellwether states in which candidates from both parties are talking about health care issues. Health care remains a top priority for Democrats and independents, but ranks lower for Republicans, behind immigration and the economy and jobs. However, when it comes to specific health care issues, lowering health care costs and maintaining protections for pre-existing conditions have bipartisan support. In addition to exploring the role of health care issues in the election, the KFF Health Tracking Poll also finds large shares of voters say candidate characteristics, President Trump, and party control over Congress will be major factors in their voting decisions.
