On February 6, the Fifth Circuit heard oral argument in League of United Latin American Citizens of Texas v Abbott, 19-50214. This the case that challenges the at-large election of presidential electors in Texas. The three judges are: William E. Davis, a Reagan appointee; Jerry E. Smith, a Reagan appointee; and Carl E. Stewart, a Clinton appointee.
Here is a link to the oral argument, which lasted 31 minutes. The recording is quite faint.
Is this challenging “winner takes all”?
If so, I doubt it will succeed.
