i am not trying to defend him but i wanted to throw a few things out for thought. If he is in the know and the bill was never going to pass the house anyway it could be a political move. dont forget we need some of these people to get reelected. in moderate districts and states moves like these can diffuse dem talking points. for example voting yes on a bill you know is never getting past the house anyway can protect from certain attacks from the left. no he cant be accused by the moderates of bailing on ukraine. there are still a lot of sheep out there that are buying that we need to fight russia through ukraine. this was just an example. another is if grassley is on his way out and served his purpose it could fire up republicans to get out to vote for a MAGA candidate after feeling betrayed. I look at it a lot like poker. there are a lot of people at the table and dont forget the bluff. if he is a white hat him voting yes can empower others to show their cards.

or he could be bought and sold just like the rest. this movie is crazy
