A third party candidate has absolutely no chance - none! Bloomberg is a liberal. From where will he take votes? From liberal democrats “fed up” with Barak Obama? Why would a liberal vote for Bloomberg when he can have the real thing? Why would a conservative vote for Bloomberg when...you get the idea.
Ross Perot was a phenomenon of his times - we were in the midst of a recession with widespread discontent towards Goerge Bush and government in general.
From the article:
“I’m absolutely in touch with leaders in all 50 states who want a third party established,” said Mr MacKay.
I suppose this should be differentiated from being 'tentatively in touch', but I'm not sure on what grounds, considering they didn't even bother to specify WHICH "leaders" he is referring to. Leaders of third parties? Sure.
On a similar level of coherence, I'm sure that if you were to be "absolutely in touch" with manufacturers of tinfoil hats, you would be able to get a clear feeling that they want the wearing of tinfoil hats mandated worldwide..
