The Clinton supporters have every right to boycott the site if they wish. I didn't visit the site when the bloggers were supporting Edwards- I was backing Obama then. After Edwards dropped out, I came back to see who the bloggers were supporting now, and, after the transition, I made the pilgramage to the Rec list daily.
It's simplistic to blame Clinton's misfortune on a site like DailyKos. I, for one, has had enough of the Hillary is more experienced, Obama is powered by crazies, logic of the mainstream media. Clinton supporters may be driven away because of the Obama-bias, but I would not have returned to the site daily if not for it. And for the record, I don't visit any of the ads on this site and I'm sure most of you don't either. We don't need a team of Obama bobbleheads who sing his praises, but the arguments by the Clinton supporters have been far from logical, for the most part. ("Yeah, winning in Idaho and Alaska will help the Dems win in November. Right.") We have a right to voice our opinions and if we don't like it, fine, that's capitalism. I know that I won't be visiting MyDD anytime soon. But, heck, my record of visiting that blog has been negligible in the first place. So, if you've got a good point, Clinton supporters, then make it. (25% of us will defect if you nominate him! You'll alienate feminist democrats!)
