I have heard even moderate Dems claim on multiple occasions that Bill Clinton should have chosen Tom Harkin as VP instead of Al Gore. Not so much to build a broader ideological coalition(Harkin was to the left of Clinton and Gore) but Harkin would have been setup better to win in 2000 especially in Iowa.
I am pretty sure Roy Cooper has already taken himself out of consideration.
