While I have no doubt McConnell would be delighted to block a Biden justice, I also think teasing his intent this way reignites all the expand the court pressure, which is definitely a “radical idea” the GOP wants to run against next year.
Mitch thinks getting the Dem base fired up on yet another obviously necessary move that Joe Manchin will kill is a win for his side. If protecting voting rights is impossible, I’m not sure how we get to expand the court in the next year.
