I like how you decide who “wasn’t a true Whig” or “was a Democrat at heart”. Clears up any untidy rubble that might interfere with the authorized version. I expect History By Seance to arrive soon, to better confirm those judgments.
The Whigs expelled Tyler after he vetoed too many of their bills, and they tried to impeach him. He wanted to go back to the Democrats, but they didn’t want him either.
