A few points...
I think Kalawao casts its votes with Maui County (after all, it's the only county in the nation that is administered by the state instead of local government)
Alaska doesn't have counties!!
I'm pretty sure it is Loving, which at the last census had only 60 something residents. Trivia note! In 1992 Loving was one of the handful of Texas counties which voted for Perot!
Ah, but that was my point.
Kalawao is legally a county, but no votes are attributed to it.
Hence, fewer votes than Loving.
You cann't get lower than zero.
