No, first of all I would
not make a good elected official of
any kind!
But secondly, I would like to point out that there is a large difference between lying and exaggerating. And anyone who cannot tell the difference is asking for trouble. Any TV producer who cannot tell the difference would be ( in this country, at least ) asking for a large, large, lawsuit. I don't know what the laws about this are in the U.K., but even here in lawsuit-unfriendly Texas, this kind of television program would have the company in court fairly quickly.
Maybe this is one reason why Clarkson decided that a TG/USA program was not something with which he wanted to be directly involved.
