The mystery of Joe Biden's five GOP senators

In talking about his struggles to bring bipartisanship back, Biden recounted that: “I’ve had five Republican senators talk to me, ‘bump into me’— quote, unquote — or sit with me, who’ve told me that they agree with whatever I’m talking about for them to do. ‘But, Joe, if I do it, I’m going to get defeated in a primary.'”

Which, well, intriguing, right?

So who are the Biden 5? Well, Biden wouldn’t name them — a reporter asked — but we can probably make a few educated guesses. (For the purposes of this thought experiment — which is purely speculative and not based on any inside information — I am assuming Biden was telling the truth about candid but unreportable conversations with GOP senators.)

Start with the seven Republican senators who voted to convict Donald Trump at his impeachment trial for his actions (and inaction) on January 6, 2021 — since they’ve already shown some unhappiness with the former President.
