Nah. Politics doesn't play into judicial decisions at all. Anyone who thinks otherwise is just plain foolish.
It's a total coincidence that, in this immigration case, the ones who dissent from the denial of the petition for rehearing en banc are Judges O'Scannlain, Kozinski, Kleinfeld, Tallman, Bybee, Bea, Callahan, M. Smith, and Ikuta. And that the other judges don't.
A totally random group of folks. With nothing at all in common. On either side.
