So we have three Supreme Court rulings today. In a nutshell:
Can we read any tea leaves here? Probably not. The immigration ruling was a patchwork compromise. The campaign spending ruling is conservative but unsurprising. The sentencing ruling is basically liberal, but also unsurprising given past rulings. There's not much insight here into how they might rule on Obamacare. But we'll know soon enough anyway.
UPDATE: More on the Montana campaign finance law here from Andy Kroll.
