On August 9, a U.S. District Court in Massachusetts heard Lyman v Baker, 1:18cv-10327. This is one of the four cases around the country that challenges the constitutionality of a state law, requiring that state’s presidential electors to be elected at-large. See this story.
A similar case was argued in U.S. District Court in Los Angeles last month. David Boies argued both times. He is famous for having been Al Gore’s attorney in 2000 in Bush v Gore.
