My utterly trivial quibble is that Goldwater did carry Arizona, his home state. The Confederacy claimed Arizona, but it wasn't a Confederate state.

Before the two thirds rule at the Democratic convention was repealed (under FDR), a united South had a absolute veto over the Presidential nominee, so in all fairness it could be blamed for the nominees of the Democrats up to FDR. I'm confident you would agree that the worst has happened since then. Ending the two thirds rule was the beginning of the end for the Democrats' Solid South.

During the period between the civil war and FDR that effectively means two Democrat presidents to "blame" the south for: Woodrow Wilson and Grover Cleveland. Wilson was elected only due to the unusual circumstances of TR's run in 1912 and Cleveland was one of the best presidents we ever had.
