I was watching CSPAN the other day, and they ran a clip of a British TV interview with Tony Blair. It was completely unlike anything that is ever seen on American TV. The interviewer was asking tough questions, and when he didn't get an answer, he kept asking the question again. It was more of a televised debate than an interview, and it was fascinating. And it was with a reporter, not one of Blair's political opponents. Our actual presidential debates don't get that substantive.
Of course, Blair was able to hold his own. Bush would get up and leave the room in a panic if a reporter spoke to him the way the British reporter was speaking to Tony Blair.
