Perot is not a lunatic.
He has a firecracker temper, to be sure, and he speaks his mind. We are not used to people REALLY doing that in the political world.
He's a brilliant businessman, and when people who worked for him were kidnapped in Iran, he put together, with his own money, his own private commando operation that went in and got them out. He is unapologetically loyal to the things he believes in.
This did not mean, perforce, that he was going to be a successful politician, but the fact of the matter is that he was a loyal naval officer, a brilliant businessman, and exceptionally loyal to his people. In the 1992 campaign he said a bunch of things that a lot of people thought but that neither party offered, and he got nearly 20% of the vote on account of that.
So, while one may dislike Perot's political style, to call him insane is too much.
LOL! We agree that Perot is a certifiable lunatic. :-)
But I would sooner vote for Giuliani than others that you mention. Giuliani has run a successful business and successful administration. His baggage could be scary-- it's hard to imagine if there's much of the Kerik stuff there.
