So this time the White House really lost a battle, right? In the wake of overwhelming public pushback against his deeply-unpopular policy of separating children from their migrant parents, President Trump on Wednesday signed an executive order to allow detained families to be housed together. Given how reluctant this administration is to ever admit error, backing down in this manner would seem to suggest that the administration grossly miscalculated. Such a comforting conclusion is unfortunately premature. First of all, it's too soon to call the president's executive order a retreat.
