What's the Deal with Edwards' Bloggers?

I guess it just got a whole lot harder to be a blogger. Now a second blogger for the John Edwards presidential campaign has quit after pressure from conservatives apparently accusing her of writing anti-Catholic blogs in the past. This follows less than a week after another blogger for the Edwards' campaign had resigned following similar attacks from conservatives. Are we witnessing the first salvos in what will be a vicious war in the blogosphere? Perhaps, this is simply a backlash against bloggers. More likely, I believe, we are witnessing in addition to the rapid decentralization of media power, a decentralization of politics, itself, to the point which people so far removed from real power are being attacked, that it's hard to know where this will end. Maybe this will result in better vetting of campaign bloggers. Of course, how many bloggers would get past the kind of scrutiny that is routinely applied to our national politicians? And isn't the whole point of blogging in the first place that it's regular people?
