Bloomberg?

A couple of reasons why Bloomberg could really shake things up. First of course is the money. Bloomberg stated he had $500 million he could spend, admitting later that he said this just to give people a number to talk about. In reality he could spend significantly more than that. Perot spent $65.6 million of his own money in 1992. Secondly, Perot never wanted to be President. He was cajoled into running, and wanted to make a statement, not actually win the job. If Bloomberg was in it to win it, he would listen to his staff and run a disciplined campaign. Big money and a will to win always has the potential for an explosive campaign.

Here's what Dick Morris has to say on his blog:

If Mike Bloomberg decided to run for President, he would have a strong chance of winning the election. As a social liberal and a fiscal conservative, he fits what most Americans want. And, unlike Ross Perot - the last Independent candidate for President - he is an experienced politician who has succeeded in handling the second toughest press corps in the world in NYC. If he ran, he would not just be a spoiler, but would have a serious chance of becoming President.
