On April 13, the Seventh Circuit heard oral argument in Hero v Lake County Election Board, 21-2793. The issue is whether the Republican Party had a right to exclude a candidate for local partisan office from its primary, based on his views about eminent domain. Here is a link to the oral argument. The judges were Ilana Rovner, a Bush Sr. appointee; Diane Wood, a Clinton appointee; and Amy St. Eve, a Trump appointee.
