“I had a colleague of mine say there’s no way Elizabeth Warren or Susan Rice could ever get confirmed,” said one GOP senator.

The lawmaker said “it would be a fight” if Biden tapped Warren, Sanders or Rice.

Some GOP senators think Warren could get through because of her credentials. Even critics acknowledge the former Harvard professor is an expert on financial regulation and an accomplished policymaker. Sen. Tom Cotton (R-Ark.), one of the chamber’s most conservative members, was a student of Warren’s at Harvard.

If Biden nominated Warren as Treasury secretary and the Senate held a vote, some senators think she would easily win 50-plus votes.
