There are a few who do, Mr P. I may have my issues with Jim McDermott, but he's from our state, from my congressional district, and he's my fucking Congressman. He said NO!
I saw him at an event a few months after. He looked beat up... actually, he got beat up at our event. I felt bad. As he walked out to his car, I stopped him on the sidewalk, shook his hand and thanked him for doing the right thing. He's one of the few who did.
