My thinking: it will never pass.
The process for passing an amendment is simple and clear. First, the House and Senate must each pass it with a two-thirds vote; second, three-quarters of the state legislatures must pass it.
The Republicans control just over half of the Senate, and a similar ratio in the House. There is no way enough Democrats will defect to get it through Congress.
Even if they somehow do, the states are a much larger hurdle. Right now, states are split roughly 50/50. The likelihood that half of the Democratic legislatures will defect approaches epsilon.
So get pissed about it if you want, but keep this in mind: it won't matter, because it won't happen.
