It’s very easy to figure out if you pay close attention to the individual states, what party maintains the legislative majority and those in the power structure. Texas, for example, would be sending two RINOs to the Senate — Karl Rove (as a thank-you to Dubya, much in the same way that Ohio sent Mark Hanna as a thank-you to President McKinley) and David Dewhurst (as the sitting Lieutenant Governor, who pressured virtually the entire GOP caucus into endorsing him for the race over Ted Cruz — and thank heavens that the people and not the elitist politicians had final say over that race).
This is the reality of what a repeal would mean, and that doesn’t even begin to cover the rest of the states. Democrat states would send ultraleftist Stalinists and Republican states would send big government RINOs, each feeding at the trough trying to suck as much money as possible from the Feds (money that ain’t there). It would be a nightmare above and beyond anything currently there.
I don't think that speculation is a good reason to have removed a fundamental check and balance when the result of the amendment could hardly be viewed as positive. Our freedoms have diminished greatly in the last 100 years, far more than they had in the previous 100 years, and this was certainly part of the problem.
