The 17th will never be repealed. We are hurtling towards another secession and nobody can see it coming.
Well I believe we should try everything, but that may be the ultimate ending. The problem is, we really aren’t as cleanly divided geographically as in CWII. There are good conservatives in blue states, and leftist communists in red states. Then if amnesty passes there will be a whole huge infusion of un-American people flooding in, and they will hit southern red states first because that is the nearest proximity to where they are coming from.
A new civil war will mean civil war in every city and even between neighborhoods, more like Bosnia, with no clear cut geographic “fronts” and lines to divide. Obama would love to see our country in a bloodbath with neighbor fighting against neighbor. I think we should try every possible legal means before that happens. You may be right though, it may be unstoppable if every other option is forbidden to us.
