On Tuesday, July 10, attorney David Boies argued in U.S. District Court in Los Angeles in a case charging that the winner-take-all system for choosing presidential electors violates the Fourteenth Amendment. Ridriguez v Brown, c.d., 2:18cv-1422. Boies is famous for having represented Al Gore in the U.S. Supreme Court in 2000 in Bush v Gore.
Here is a four-minute you tube by a witness to the recent oral argument in Los Angeles. The judge is Consuelo Marshall, a Carter appointee. She was hearing the California government motion to dismiss the case. Apparently, during the argument, she said very little to indicate what her attitude is toward the case.
There are similar cases pending in Texas, Massachusetts, and South Carolina, but none of them have had oral arguments yet.
