Been there, done that, your side lost. Remember Prop 187? Learn your lesson.
"your side lost"
uh..Remember Gray Davis, recalled by democrats and republican both over this same issue?
And what lesson would that be? That the Judiciary are to be regarded as unopposed dictators? That the will of the majority can be wiped out at a stroke of the pen, and we should roll over and take it? That the Federal government can both refuse to do their Constitutional duty to protect the borders and simultaneously deny the States and the People the means to pick up their slack?
What I'd truly love to see is the AG of some border state sue the Feds for the costs incurred because they haven't controlled the borders. It seems there is actionable cause under Article IV, section 4, under which the Feds are required to "protect each of them [States] against Invasion."
