I have very little respect for either of the men in the photo above. "Independents" and "mavericks" have very rarely added anything of substance to the field of governance. These two are no exception.
That said, it is an interesting historical note that Joe Lieberman (now wearing that (I) behind his name) is now the most powerful man in the Senate. Senator Tim Johnson's recovery appears to be proceeding well but anyone who understands the potential ramifications of the injury involved would have limited expectations of seeing him on the Senate floor this year. Hopefully, he will make a full recovery but it is a very long process.
Good ol' Independent Joe can stroll accross the aisle in a 50-49 Senate any time he feels.. well, independent, and there is not one damn thing the Dems can do about it. Will the thrill of such independence lead to the creation of an Independent Maverick Party? Given the egos of the men involved, it's a definite possibility - especially if Giuliani is still outpolling McCain by September.
Would such a third party run occasion a vote split that would give us the horror of a third Clinton administration? That would be a very likely outcome. If it occurrs I'll be happy to place the responsibility at the feet of 'Keating Five' Maverick McCain.
