According to polls by Morning Consult, "51 percent of members of the military surveyed would vote for [Donald] Trump, compared to 36 percent for [Hillary] Clinton." Those numbers become 52% for Trump and 39% for Bernie Sanders. Among veterans, it's a steady 47% for Trump, with 38% for Clinton or 43% for Sanders.
A Military Times' poll of active-duty troops, reservists, and National Guard soldiers gives Trump 54% against Clinton, 51% against Sanders.
Military leaders are scared shitless over the idea of a Trump presidency. The troops themselves? Not so much.
Now, obviously, May polls are, as this blog has said, utter bullshit in many ways. But the support for Trump among the rank-and-file military has remained consistent for much of the year.
In any case, we can be pretty sure that Memorial Day during the Reign of Trump will be filled with even more mourning. And he'll have a fuckload of support should he need to take over by coup.
