In what appears to be one of the most interesting posts I've read yet by one of the groups of protesters organizing to attend both the 2008 Republican National and Democratic National Conventions, "Unconventional Action North Carolina" wrote a letter to the participants in the January 2008 Consulta in Denver, an event where several of these groups converge to plan their protests. In it they voiced several concerns, including:

We are concerned that, on a national level, the organizing against the Republican National Convention seems to be further along than the organizing against the DNC. If this continues, we fear that many more anti-authoritarians will attend the RNC than the DNC, as occurred in 2004. This would be a tremendous missed opportunity, on a number of levels. First, it would give the impression that anti-authoritarians are simply the radical fringe of the liberal establishment, opposing Republicans but leaving Democrats unchallenged. This essentially lets the Democrats off the hook for their complicity in the occupation of Iraq, the assault on civil liberties, and the exploitation and ecological devastation inflicted by industrial capitalism; now that the Democrats seem poised to take the reins of the executive branch, it is more important than ever to show that we offer a concrete opposition to party politics, not just Republican excesses.

I suppose that is a significant problem, if you as a protester, do not have the same amount of protestsers at both conventions, it looks a bit-- unorganized and unorthodox--not to mention the "missed opportunity."
