We will thus affirm the District Court’s
denial of leave to amend, and we deny an injunction pending
appeal. The Campaign asked for a very fast briefing schedule, and
we have granted its request. Because the Campaign wants us to
move as fast as possible, we also deny oral argument. We grant
all motions to file overlength responses, to file amicus
briefs, and to supplement appendices. We deny all other
outstanding motions as moot. This Court’s mandate shall issue at
once.
