Gay marriage has a lot of discussion but actually little in the way of litigation. This California thing is a tiff between courts ~ more or less ~ and it involves California's almost unique public referenda system.
Whereas maybe gay marriage is a national issue we have 30 states that've already outlawed the practice. Justices concerned for the USSC's reputation for proper consideration of cases is on the line here ~ which, the theory goes, is how Roberts sees all the cases. He wants to make sure they don't run off half cocked against the national will or interest. Fur Shur that'll be the beginning of a campaign to depose them one way or the other (and by depose I don't mean that we just impeach them ~ more like displacing the USSC from the national dialogue).
Going through Robert's decision in ObamaKKKare vs. the people of the USA he made a simple judgment ~ go with Congress, but change the basis of the system to screw up the Democrats because they will never figure out how to use it as just a tax ~ then any later court can knock their more outrageous nonsense out of the air like wiffle balls.
He'll lean that way here ~ so will 5 or maybe 6 others.
Thank you!
