BTW… when you cast your vote in the U.S., it’s done anonymously.
Yes, you hafta show up and present your voter registration card (unless you’re illegal, of course) but the ballot you cast has no personal identifying information on it.
Even if someone wanted to revoke your vote, it’s not possible once it’s been cast.

Caveat: With electronic voting machines on the rise, this guarantee might not necessarily hold true in all cases.
Ohhhh… and I didn’t take absentee voting into account (where you mail it in). I was talking more to early voting where you physically show up at a polling location prior to Nov. 4.
