Very good summary of Whigs John...btw old Henry Clay, who I believe was one who started the Whig party was 1st cousin of two of my ggg grandmothers.
The father of Thomas Hart Benton was a big supporter of old Andy Jackson `til they fell out & fought a duel...thats when he took off for Missouri...His Son (by the same name) was a Unionist but he soured on them and he was the one who painted the mural titled "order No 11" which is in our state capital in Jeff City.
