I have warned of this stuff before, but this is too good ...
That's why I find it good that here in Austria, and I guess also in Germany, the government or your town sends you your voter information card via post, with which you have to go to the polling place, shows a valid government issued photo ID (only passport, driving license, personal ID counts) and then you get your ballot there and can vote.
Well,
de jure, at least. Our little town in Southern Hesse (at least in my precinct) never really checks IDs.
