Calhoun was a Democrat. Tyler was transgender.

Okay, not really, but he was basically an ideological Democrat who ran as a Whig because of quarrels within the Democrat Party.

Tyler opposed Andrew Jackson because Jackson wasn't "state's rights" enough.

Many slaveowners were Whigs, but the most ferocious secessionist fire eaters were usually Democrats.

“Tyler opposed Andrew Jackson because Jackson wasn’t “state’s rights” enough.”

He prolly had a point, seeing as Jackson was about to invade South Carolina over the nullification crisis. If that had ever been adjudicated it might have provided clarity regarding the issue of secession. Unfortunately it was rendered moot.

Charles Francis Adams Jr, scion of two Presidents and himself a Union officer, researched secession after the war for his own curiosity and concluded that “both sides were right”- that the issue of secession was ambiguous. That the founders ratifying the Constitution did so while believing that their states retained the right to withdraw from that union. But that a few, including Washington, believed otherwise. It’s in an essay Adams delivered in 1902, “Shall Cromwell Have a Statue?”
