Can't say for sure but backroom deals are made. He is in a heavily democratic district. Maybe the party let him vote for it knowing they wouldn't win even with his vote.
There’s absolutely NO excuse for voting for this POS. It’s called “PRINCIPLE,” and you NEVER compromise on your principles. NEVER!
And if the Party allowed him to vote YES, then we have even more work to do to clean house at the RNC. Steele should pay with his chairmanship if this was allowed!
