The Wisconsin Elections Commission says the federal government is threatening to sue because this state doesn’t let temporary overseas voters file unofficial ballots or get their ballots electronically. A letter from the U-S Department of Justice was received two weeks ago. Federal law allows voters living outside the country — short-term or long-term — both options. The U-S Attorney General’s Office is demanding the state of Wisconsin sign an agreement promising to provide those options. The letter is on the agenda to be discussed at a meeting tomorrow (Thursday) at the Capitol.
