How do Amish people vote?

[Oldiesfreak1854]

I thought Amish people are Mennonites, and isn't one of the fundamental beliefs of their church that they abstain from participation in government?

Maybe I'm confusing them with Jehovah's Witness, but I'm not entirely sure.

I know here are some differences between Amish and Mennonites, although I can't think of any off hand.  I also know that Jehovah's Witneses don't vote, sing the national anthem, serve in the military, or salute the flag.
