As near as I can tell, this is the Trump Administration’s strategy in a nutshell:
1) Block testimony and refuse to cooperate in any way with the House impeachment inquiry, forcing the Democrats to impeach based solely on obstruction.
2) When the Senate hearings start, Trump lawyers will then say, “The House Democrats were politically motivated and provided no evidence.”
3) The Republicans in the Senate will put party before country—as they always do—and quickly dismiss.
4) Trump’s Christian-right supporters will enthusiastically declare that God intervened on Trump’s behalf.
Then it will be up to America’s voters to overwhelm the GOP’s dirty tricks and cheating in the 2020 election to prevent us from becoming Western Russia.
