In a nutshell: It limits the ability of #darkmoney groups to keep their donor lists secret this election. /1
/2
8/3: Trial court rules @FEC regulation allowing #darkmoney groups to hide donors is illegal. Delays killing reg until 9/17.
9/15: DC Circ. declines to extend that delay; Chief Justice Roberts *does* extend it.
Full #SCOTUS just flipped that: The reg is dead. /3
