Healthcare is still the top political subject for voters less than a month before the 2018 midterm elections, according to a new national poll, but perceptions of President Trump are also a major consideration.

The Kaiser Family Foundation poll released Thursday found that 71 percent of voters called the issue of healthcare “very important.” The poll also found that voters in Florida and Nevada favor candidates that seek to protect coverage for people with pre-existing conditions.

The findings are the latest evidence that Democrats are well-positioned to benefit from unpopular GOP attempts to repeal Obamacare.

There were 64 percent of voters that listed jobs and the economy as “very important,” and 60 percent listed gun policy. The poll allowed respondents to choose among several issues.

When asked to pick only one issue as the most important, healthcare topped the list again with 30 percent of voters, compared to 21 percent for the economy and jobs.

While healthcare dominates, attitudes toward President Trump will also be a top factor in voters’ decisions, the poll found.

Two-thirds of voters (66 percent) say that a candidate’s support for or opposition to Trump will be a factor in whom they support. However, the poll did not break down whether voters are more or less likely to support a candidate who is for Trump.

In addition to covering national issues, Kaiser looked into bellwether states Nevada and Florida, which feature Senate races that could determine the majority next year.

The poll found that 69 percent of voters in Florida and 68 percent of Nevada voters would be more likely to support a candidate that wants to maintain Obamacare’s protections for pre-existing conditions.

Pre-existing conditions have become a major flashpoint among key races in the 2018 midterm elections. Democrats have charged that Republicans are in favor of revoking pre-existing condition protections as part of their effort to repeal Obamacare.

The national poll was a survey of 1,201 adults with a margin of error of 3 percentage points. The Florida and Nevada surveys were of 599 residents in each state and both polls had a margin of error of 5 percentage points.
