Republican voters are most interested in hearing from congressional candidates running in this year's midterm elections about provocations by North Korea, according to a new survey.

Nearly a third of GOP voters, 31 percent, said that the situation with North Korea tops their list of priorities in the 2018 midterms, the Kaiser Family Foundation poll finds.

North Korea is followed by immigration, with 27 percent calling that the most important issue. The economy and jobs came in at a close third among GOP voters surveyed, at 25 percent.

Democratic voters and independent voters, on the other hand, put health care at the top of their priorities lists for the 2018 midterm elections, at 39 percent and 32 percent, respectively.
