A democrat that can win all of Oklahoma's counties except for three can win a GE. The problem is he has no chance in a primary.
This comment is pretty dumb, really.
Coalitions have changed dramatically since 2006, and someone who can win over rural whites would probably lose the election by turning off suburbanites and making minority turnout plummet... on top of this, he would only do a little bit better with rural whites than a generic D, most of these voters are not going to vote for a Democrat under any circumstances. compare how Phil Bredesen did in the 2002 or 2006 Gubernatorial elections to how he did in the 2018 Senate election.
