I have a lot of theories as to why, but no point talking about that now. What you need to do is react intensively to this:
If you have a state initiative process, start an initiative now.
Plan and support a "recall Huckabee" movement. We did here in California, and we won. Anyone who thinks it wasn't 80% about the illegals is dreaming. You only have to convince a few million predominantly conservative voters to go along with you.
Start an organization that can take this to court. In Kansas, Kris Kobach has a lawsuit going which will most likely take down the Kansas law which is similar. College for illegals violates the vaunted 14th amendment in that it discriminates against U.S. citizens.
And on and on. Contact ProjectUSA (Craig Nielsen would be happy to billboard your state), NumbersUSA and FAIR. All of them are aware of this and will help.
It's up to you to establish your freedom from taxation by Mexico's murderers (the "Mexican government", if that's what it can be called), because that's what they are doing: offloading their responsibilities on you. Don't let them.
If Mexico were forced to pay for 1/2 of everything they demand we provide for illegal Mexicans, they would be forced to reform.
And this board's favorite - GW - is one of those elitists.....
