How to neutralize Mitch McConnell?
Do what George Marshall and FDR did to Douglas MacArthur: get him out of the country so he can't screw things up for the national agenda. MacArthur hated FDR, thought Marshall was weak and Eisenhower was a pencil pusher, and if he'd been anywhere near the Washington press corps he would have done everything he could to undermine Eisenhower's leadership in the planning for D-Day and the liberation of Europe.
How to do this to McConnell? Simple. Appoint him as ambassador or the equivalent to Taiwan, and make the announcement without asking him to accept the position. He's married to a Taiwanese-American, after all, so on paper it would be a great match. The public pressure to accept would be enormous whether he wants the job or not, the pressure from his in-laws would be even greater, and the Taiwanese government would regard his refusal as a personal affront.
Even better? Being sent off to his wife’s homeland would also be a capstone for Elaine Chao’s distinguished career in government. Neither of them is particularly young, so being honored for their service and pleasing the Chao family would be an ideal solution.
Sounds like a win to me.
