The unraveling will take time, as it isn’t the Presidency as much as it is Congress where things are skewed red.
That is why the big worry for Republicans isn’t the White House, it is traditional Republicans staying home and not voting on the down ballot offices.
If they hold the House and Senate, then Trump is just a nightmare. If they lose Congress, they will be worried about being a national version of California, where all state offices are Democratic as are both house of the legislature.
What may be a better indicator is the results of yesterday’s Kansas primary, where the Brownback wing of the Kansas Republicans got thrashed, including a vocal member of the Congressional “Freedom” Caucus. John Boehner was laughing at the obnoxious Freedom Caucus firebrand that lost yesterday to a more moderate Republican.
