I agree. As soon as I heard Corker, I thought ‘liberal’. And then it was obvious. The Senate doesn’t need to pass a bill that can be vetoed by the president. The Senate has a constitutional power to advise and consent on any treaty. The threshold for that passage is 2/3rds.
This also explains Schumer’s support, as if he actually went against Obama. This scheme of Corker’s ENABLES Obama.
