The states have never amended the Constitution to expressly protect abortion, gay marriage or same-sex reparative therapy. So while upholding 10th Amendment (10A)-protected bans on same-sex therapy actually works in the favor of pro-gay activist justices, the Court was hypocritically wrong to ban 10th Amendment-protected prohibitions on abortion, likewise for gay marriage if the Court overturns state bans on gay marriage.
The 17th Amendment needs to be repealed so that state sovereigny-respecting justices can eventually overturn the corrupt Court’s wrong ignoring of the 10th Amendment on abortion and gay marriage if pro-gay activist justices legalize gay marriage from the bench.
I've said it before and I will say it again, the notion that some sort of ideological purity exists at the state level that can fix our federal problem is absurd.
Members of state legislatures are very influential in state party politics and play a major role in who is nominated for state office to begin with. When Dave Brat defeated Eric Cantor in Virginia in last years GOP primary, this was done at a GRASS ROOTS level, the Virginia General Assembly and Senate would have NEVER gone along with it if given the choice.
If anything, eliminating the 17th Amendment will make things WORSE because candidates for Senate will no longer have to deal with primaries, they can cut deals directly with the party bosses in the state legislatures.
Ideas like this and a convention of the states sound great in theory, but in reality they will accomplish nothing.
