Their MO is bonehead and I'm hoping they do another. It betters the chance of this going nationwide. I don't think Roberts and Alito are going to vote for cert unless they get a favorable read on Kennedy and the four liberals think he's too much of a "conservative" to trust him on guns.
I think the fact that peruta was denied means Kennedy may have hinted he would vote against whoever forced cert. There was at that point not two outcomes, ending may issue or not, but a third -- leaving it ambiguous. But I think from the complaints from Thomas after that Kennedy's threat was more tilted against shall issue.
The issue is now different now though with it being more of a circuit split which is more compelling in terms of cert.
