Possible Future SCOTUS Nominees over the Next Four Years(Exclude Garland)

[Heisenberg]

Of the ones that you mentioned, Pat DeWine would make a fine justice, IMO. I'd prefer judges who have had experience on courts, and not those who had been in politics (they would probably be viewed as a little too partisan during hearings). Of those you listed, JBE is one exception, while he is doing a good job as governor and is not too partisan, governors are not SCOTUS justices, and I can't see a Republican appointing him, he is a little too pro labor and pro regulation (from what I hear). As a Republican, I would take Brian Sandoval (even though he is to the left of JBE, socially) over JBE in a heartbeat. Sandoval would also be more likely to retire under a GOP administration, while JBE would likely do so in a Democratic administration.

Here's a good list of Conservative Candidates for the Supreme Court

Keith Blackwell Georgia Supreme Court Justice

Charles Canady Florida Supreme Court Justice

Neil Gorsuch Judge Tenth Circuit US Court Of Appeals

Mike Lee Senator from Utah who used to be Assistant US Attorney from Utah and he's on the Senate Judiciary Comittee

Edward Mansfield Justice Iowa Supreme Court

Federico Moreno Judge US District Court Southern District of Florida

Margaret A Ryan Judge US Court of Appeals for the Armed Forces

Amul Thapar Judge US District Court Eastern District of Kentucky

Timothy Tymkovich  Chief Judge US Court of Appeals Tenth Circuit

Robert Young Chief Justice Supreme Court of Michigan

Other than Blackwell nobody on this list would be as controversial as a Sykes or Pryor. Could see some red state Dems backing Gorsuch, Ryan or Tymkovich for example

Mike Lee would be controversial: partisan elected official, and would face the Senate, which he's part of. Judges only (but that's my opinion).
