This should be especially worrying to Donald Trump -- and to Republicans. Those counties with a lot of military families traditionally vote Republican, and those counties voted for Donald Trump in the 2016 election. But it looks like Trump is now losing support in those counties.
After he was in office for 100 days, those military counties still gave Trump a net approval rating (approval minus disapproval) of +7 points. But that same poll (done by Gallup) in May has Trump with a rating of -9 -- a huge shift of 16 points.
These are not voters that Trump, or the Republicans, can afford to lose. If they don't turn this trend around, it could be very bad for them in 2018.
