It's not the only policy being doubled down on

"Both sides are the same" is not the argument here. It's "militarized and cruel border policies are bipartisan".

edit: I should also mention: there's a real pressure building here. Not only are our south and central-american policies creating refugees and mass migration, but increasingly climate disasters, too. Clamping down on the boarder is the reactive thing to do in response to the number of migrants showing up, but the real work needs to be assessing broader international policy and aid to our southern neighbors, and that's another policy area where the current administration seems stuck in the past
