The data also suggest that military personnel have not been dissuaded by political rivals who contend Trump and Sanders have weak foreign policy credentials and don’t have recognized experts as national security advisers.

In the poll, nearly half of the service members surveyed said they were unhappy with the discussion of national security issues in the presidential race so far. Fewer than 5 percent were “very satisfied” with how the topic has been broached.

Florida Republican Sen. Marco Rubio, who has made national security issues one of the centerpieces of his campaign, was nearly last in the Military Times survey, with only about 9 percent of candidates favoring him. Texas Sen. Ted Cruz had almost double that, with 17 percent support. Those surveyed offered only slightly more support for Republican Ohio Gov. John Kasich (8 percent) than potential third-party candidates (6 percent).
