Following up on this post, VRTL attorney Jim Bopp told the election law listserv (and reprinted with Jim’s permission): “The 2nd Circuit has very restrictive rules on granting rehearing so they never do (to my knowledge). They did not even grant rehearing in Randall v Sorrell. So off to the Supreme Court with a big Circuit split on both the PAC and IEPAC issues. Jim”
I give this a reasonable chance of a cert. grant, given the circuit split (though not on the disclosure issues, but on the coordination/enmeshment issue).
