Why did the Republicans vote no on the UN treaty ratification on disability rights for other countries?

It's unclear. They seem to be concerned about their re-election, as their base does not like the UN. However, the treaty is based off of our ADA. It changes nothing about our current law and lacks any reinforcement. This treaty only contains recommendations on how to treat people with disabilities, and since we already have it in our law, it would change nothing to our current situation. In addition, no UN treaty could usurp our constitution. The congress needs to ratify it with a super majority (66 votes), and if it were challenged, it could still go to the Supreme Court to determine constitutionality. So, the concern about sovereignty is unfounded. The republican's base seems to believe in conspiracy theory (UN actions can't over-ride our own constitution-so, really there's no worry about sovereignty), disdain for anything UN related (even things we sanction and are about human rights in other countries), and ignorance. Where all this comes from, I can not answer.

@Bomb Yo Kang: I feel... Defeating this ratification as a disabled/dying Bob Dole looks on is mocking the disabled. You know, given that he's there to aid it, as someone who was as soon as very powerful in his social gathering; and his get together defeats the bill. And the invoice isn't controversial. That is why lots of the planet Earth has signed and is ratifying it. Discover that the "The treaty also was extensively backed by way of the disabilities group and veterans organizations." and used to be backed with the aid of former soldiers within the republican party.

The Republicans are now attached to their brown shirts.

The ruling would have cost us our sovereignty. It would have made it mandetory for parents of disabled kids, that they couldn't do anything without approval from the United Nations. No thanks!
