While the longest government shutdown in U.S. history continues, President Trump’s approval rating is down, and there are cracks showing with his base.

A new NPR/PBS NewsHour/Marist poll finds Trump’s approval rating down and his disapproval rating up from a month ago. He currently stands at 39 percent approve, 53 disapprove — a 7-point net change from December when his rating was 42 percent approve, 49 percent disapprove.

And the movement has come from within key portions of his base. He is:

• Down significantly among suburban men, a net-positive approval rating of 51-to-39 percent to a net-negative of 42 percent approve, 48 percent disapprove. That’s a net change of down 18 percentage points;
• Down a net of 13 points among white evangelicals, from 73-to-17 percent approve to 66-to-23 percent approve;
• Down a net of 10 points among Republicans, from 90-to-7 percent approve to 83-to-10 percent;
• Down marginally among white men without a college degree, from 56-to-34 percent approve to 50-to-35 percent approve, a net change downward of 7 points.
