that's crazy...Kos is just grassroot liberals and they focus on news items and comment a lot...now these can sway to the extreme sometimes because it is community driven and written but generally it is just more intensive coverage of things that are being brushed over by the major media (who are hardly lefties...GE owns NBC right?) and they organize and raise funds for candidates and try to get rid of fake Democrats like Lieberman.
KOS is just organized partisans who are changing the way politics is done in this country. The Republicans are not as up to date with the current technology and are scared.
