The White House may consider the unilateral amnesty a winning move on several different levels: it gets its policy goal; it satisfies an important part of its base; and if there is any serious move toward impeachment, it rallies the entirety of the Democratic base in a way we haven’t seen since 2008 and — assuming the politics of impeachment are bad for Republicans — drives the middle away from the GOP. An administration that is fast entering its dotage could consider this one of the few potential positive game-changers that it has direct control over — the Constitution and the rule of law be damned.
