When are Republicans, not only on Capitol Hill, but in state capitols across America going to finally understand that Donald Trump being a 40-percent president, or a 33-percent president, was always going to lead to them getting destroyed in the off-year elections?

Rachel Maddow, on the last week of White House news

To the people running this country right now, Jakelin Caal's terrible, unnecessary death isn't a horrifying failure — it's a useful talking point

Chris Hayes, on the death of a 7-year-old Guatemalan migrant in CBP custody

Washington can feel where we are now. Washington can feel what is coming now. An impeachment investigation by the House Judiciary Committee is all but inevitable.
