I'll abide by SCOTUS's decisions... and the Text of the Constitution.....but I won't defend overturning long held precedent for the sake of partisan politics, all in order to ban free speech.
most likely, I'll move out of the US and to a country that still protects free speech rights.( I'm too old for revolution, and i'd like to see you authoritarian live under the hell you create)
in any event, even court stacking by Hillary won't help you to rid ourselves of free speech rights..... you'll have to get Congress in on the action as well... they'll have to change current law... or , in other words, purposefully and willfully create unconstitutional law.
without changing the law, the government can't limit independent expenditures... without limiting them, there's no standing for suit to be filed.
you'll also need lower courts in on the scam as well.
so yeah, regarding banning politcal speech, you've got your work cut out for you... I wholly heartedly hope you fail miserably, as I respect free speech immensely.
