NOTHING is cut & dry in politics.. And if you think the USSC is not a political body, think about it.
Anyway, the extreme Brady-ites probably want it to go to the SC and get some sort of anti-gun ruling out of the supremes, to get a lot of draconian things passed. Remember, the speaker of the house, if she had the ability, would like frew things more..
Basically, the brady-ites are likey viewing this a chance to "go for the juggular" so to say.. Small chance of scucess, but very low risk to them.
Pro-Freedom types, odds are, this can be a VERY GOOD thing, but the stakes are high if the Supreme Court gives some sort of wacky ruling.
Basically, the odds are in our (pro-gun people) favor, but the stakes are high if we lose. How bad it could be would range from "preserve status quo" to "the second amendment applies only to militias".
It would be definite victory if we prevail, however.
For the Anti's, it woudl be nothing but a speedbump to them, and they would twist whatever comes out to try to use it to their advantage. The have a low-risk, high reward, low odds situation..
