Do Indeed Beg Yo' Pardon, Ol' Son

A Boa that's really a Rattler. I still can't figure who this character represents. He refers to LBJ as a 'pardoner', inspiring me to check the president's pardon record. By the end of his term, it was 1187 pardons and commutations, 20% of the requests. I know nothing about this stuff, is his record above average for presidents?
