My “idea” is exactly in line with the facts. He said he was fooled by those rascally dems/reps. so, hours before the vote, changed his mind. This, after supporting with influence in the paper.
Do you even know that the version of TPA that he voted for was NOT the same version that came back from the House? And that it was the 2nd version he voted against because of the way it was changed, along with the fact that McConnell was trying to buy Senate votes by promising to resurrect the ExIm Bank?
By the way, why are you opposed to TPA, anyway? This has been around since the Carter Administration and it was just being re-authorized. I'll bet you don't really have any idea about what TPA is or does, and you either are confusing it with TPP or are just repeating liberal talking points (since the Dems unanimously opposed TPA).
