@Joey - #8 is an absolute deal breaker. We fought and won our independence. why in the hell should we go back to being under *any* form of British rule. I guarantee that would never float.
#9 would meet resistance as the general populace is sick and tired of having the Mexicans have so much control over the language and services we provide to them. You don't saa the Indians over here *legally* require us to offer Hindi, so why should we allow the Mexican population, many of whom are here *illegally* to force us to adopt Spanish?
#10 - Never happen. We set it aside so no one state could claim ownership to the federal government or have a governor have rule over the president and the courts. Having the seat of national power be part of a state invites that state to abuse it's authority and exert undo influence ont he federal government. Imagine having the governor declare martial law and taking over the federal buildings. Making it part of another states invites that kind of disaster. In fact, if we implemented #11 as you suggest, Ottawa would need to become a separate entity as well, although that (moving the Senate and Supreme Court) wouldn't likely happen either. We need the Senate and House to be in the same location for their backroom deals which is, honestly, the only way some things ever get done. Plus, when the President calls on a Senator or a Representative, he wants them in his office, not on a phone/video conference. and could you imagine every time of the Supreme Court needed testimony from a Rep, having to fly them to Ottawa. The T&M costs would be unfeasible.
