Yes, I thought the Senators were very poor and Galloway handled them easily. When you are a decade out with the exact dates of your main evidence, and spend 5 minutes rambling when asking a question you are not going to trouble a man vastly experienced in confrontational British politics and TV.
All other things being equal our pre-packaged, airbrushed, scripted American senators will lose out in open debate to rough and tumble British MPs. Those Brits aren't afraid to mix up it up with anyone including hecklers. Our Senators, by contrast, try to have the hecklers arrested.
