Although I agree with you, let me explain what that rep meant by using a real example from the 1998 law.
A rep that I know personally for lots of years told me that the speaker told him and others that if they didn't vote for the 1998 GCA that there would be retribution. He doesn't support 2A but when he read it, he told me that he couldn't vote for it. He voted against it. Prior to the vote, he had a nice office on the 3rd floor, a fair number of staffers and sat on a few committees (they get extra money for this).
After he voted NO, I paid a visit to the state house to see him again. They moved him to a basement office in a corridor where most of the lights were non-functioning, I needed my flashlight to find my way (not kidding). They gutted his budget for staff and removed him from some committees. This affected his ability to function efficiently and reduced his paycheck.
That's what happens to reps/sens who buck the speaker/senate president. It's very real. Politics is a very dirty job!!
