From Jonathan Bernstein:
Proceedings would ultimately let the president put the scandals behind him.
Democrats are again being tempted to move toward impeaching Donald Trump. It’s still the wrong call to make, at least so far. Yes, there’s a good case — a very good case — an extremely good case — that Trump has acted contrary to his oath of office and deserves impeachment and removal. With his attorney general pitching the preposterous idea that the president can just pull the plug on any investigation of his own actions, and with the president actively resisting normal congressional oversight, it’s clear that the House should be fighting back as strongly as it can. But for now at least, Republicans are not going to vote for impeachment, and so we’re talking about a partisan impeachment and a partisan acquittal.
That’s a path that has no advantages for Democrats before, during or after impeachment.
