That is: A trend of moderates in both parties -- kicked to the curb by the increasingly right-wing and left-wing powered republican and dem parties -- becoming Independents and running as viable candidates against the loony left-wingers and deranged right-wingers that the two parties invariably will place before the electorate. Just today, CNN's Political Ticker blog has a piece entitled, "More Moderate vs. Conservative GOP battles ahead" (link below), which details a number of high-profile races nationwide that are setting up as primary battles between moderates and those who would accuse them of "not being conservative enough."
I do hope that Crist's Independent turn does set a precedent that other non-conservative and non-liberal candidates across the country can look to and seriously consider whether they should run as Independents themselves. Our political system -- controlled by the two extremes (and increasingly so) -- is simply broken. We need to shake it up. And the only way that will happen is for viable third-party and Independent candidates to start running for elected office against the liberals and conservatives. I say, go Charlie and go Independents!
