Sen. Byron Dorgan (D-N.D.) has
announced that he’s retiring at the end of his term - he will not seek re-election in 2010. This will make it nearly impossible for Democrats to maintain their 60 seat super-majority in the Senate and North Dakota now becomes a likely pick-up for the GOP. In a broader context, however, Dorgan's retirement will mean that there will be one less centrist in the Senate resulting in an even more polarized Senate.
