Should California be allowed to secede from the union?

No, we went over this in the 1860's.

Ironically the US GDP would plummet if California left. I doubt very much we would let the blue states secede because the red states are - how to gently put this? - uneducated and less productive compared to the bluer states.

Basically axe NY, CA, and IL and the US would go from a super economy to a second rate one.

No, they should not be allowed to secede from the union.

They should be forced to live under a Trump Presidency, like it or not, at least for a minimum of four years.

After living four or eight years under a Trump Presidency, let them go their own way if that's what they want.

No at that point they would probably be under a Democratic Presidency. The Republican states are free to defect at that point though.
