Who can tame Trump? An unlikely candidate is emerging: the Catholic church | Simon Tisdall

Inequality, immigration and civil rights are the battlegrounds on which the church, and some other Christian denominations, are fighting

The supreme court can't do it - it's packed with conservatives who owe him their jobs. Congress won't do it - Republicans slavishly follow his orders, Democrats are ill-led and divided. For today's White House, the concept of constitutional limits on executive power is a quaint relic. The news media, or sections of it, does its best amid constant legal threats. But, too often, they pay him off. Brave reporters who insist on asking awkward questions are insulted or silenced: Quiet, piggy."

Voters may try to indirectly rein him back in next November's midterms (as they did recently in New York and elsewhere). But those elections are a year away. The emergency is today.
