Even if Democrats capture the House in the 2018 midterms and impeach Trump with a simple majority, there’s no way they can win the 67 Senate seats necessary to remove him from office. Without any Republican Senators, the effort will fail.
Whether for checking Trump’s worst impulses or ultimately removing him from office, Democrats need Republicans. Many NeverTrump Republican commentators, politicians, and voters share some of the Resistance’s concerns about the president. If Corker is to be believed, many congressional Republicans do as well, but they feel immense pressure to back the president anyway.
Resisting those pressures won’t be easy, and it would behoove liberal Trump critics to do everything they can to make it easier. If they truly believe their own rhetoric — if they truly believe that the president is an existential threat to America — then they should get over their partisanship and put country first.
