Okay, it's time to start paying attention to impeachment (akin to a criminal indictment). This article by former Bush speechwriter David Frum is an excellent place to start. It briefly outlines the perils of impeachment (if you shoot at a king, you'd better not miss). And as for the Dems, they need to keep talking about the issues that people care about and that this administration is screwing-up: health care, climate change, tariffs that hurt American enterprises (e.g,. farmers), and so on (and believe me, I could go on at length). Anyway, start here, and I"ll try to keep pace.
P.S. Am I excited about impeachment? Do I cherish the ideas of President Mike Pence? Good grief! We must ultimately act via an election and reject the politics of division.
