Does a State have the right to secede?

[L Verge]

Are we leaving out the third branch of government here? It is not the way Presidents interpret any part of the Constitution that should concern us. Above all else, throughout our history, the majority of them have been master politicians who will say or do any given thing at any given moment which will support their political agenda.

It would be more interesting to me to see what opinions/rulings have come down from the Supreme Court in the past 200 years on the issue of secession (without throwing in the race card, please).
