Just to give her a hard time, someone should research all the Senators from Massachusetts. With as much assimilation as has occurred, I’d be willing to bet there are at least a few who can claim 1/32nd or more.
I will nominate Sen Benjamin Smith (1960-62) as at least 1/32nds Native Am - of course he also resembles George Zimmerman. He finished out JFK’s term. Kept seat warm for Teddy.
