When will the next POTUS candidate win the Presidency without winning a single ex-Confederate state?

Virginia used to be a reliably-Democratic state (except for 1928) before Eisenhower won it in 1952. Then it went D in only one Presidential election (the LBJ blowout against supposed-extremist Barry Goldwater in 1964) until Obama won it decisively in 2008. Virginia seems to be going stadily more D -- so much that it voted for the Dempocrat who lost the Presidential election, and that Biden won it by 10%. 

This was not the result of a steady shift. Virginia was the only former-Confederate state to vote against Carter in 1976 (if by a narrow 1.3% margin), and it went by about 4% against Bill Clinton in 1992 and against Clinton by roughly 2% in 1996... in elections in which Bill Clinton won with 370 and 379 electoral votes, respectively.  Gore lost it by 8% in the most even election ever, as did Kerry in 2004.

Virginia is the oddity stte of the South. No nominee for President has come from Virginia since at least  1916 (Wilson was born in Virginia), so that's not a part of it. Climate? Nope. Virginia has much the same climate of southeastern Pennsylvania. Summers in Philadelphia are as hot as those in Atlanta.

Maybe Virginia isn't a real "Southern" state anymore. Besides, I see similarities of temperament and conduct in Ike and Obama; both are Realpolitik politicians in a state that has much connection to national defense.
