The 58% figure comes from This Story. Basically, the count saying that the One Nation Working Together rally was 165,000 people is bullshit. No non ultra-partisan news source has confirmed it, and pictures taken of the rally show it to be significantly less attended than Glenn Beck's. My conclusion is that the folks who ran the One Nation rally are out of touch with basic America if they can't even draw the same amount of people as Glenn Beck to their rally. It's not surprising, looking back on it. These folks are the organizations representing the old New Deal Coalition, albeit with minority organizations from the New Social Movements of the '60s and '70s added in. As such, their political reality does not reflect what's going on in America right now and probably hasn't since the '80s. That they've sort of limped on and are now coming together, with little change, speaks volumes to their strategic thinking or lack thereof. Which is not to say that all the groups that participated are wrong or ineffectual; the NAACP was part of it, for example, but it is to say that this particular strategy of depending on rump union support combined with minority organizations alone, with maybe an environmental group thrown in for some variety, is not the way to go. The overall strategy isn't working.
Instead, what we need is a broader based socialism that appeals to regular people in general, including but not exclusively aimed at white working class voters. Socialism in particular needs to cut itself loose from the old union movement and forge new ties with folks on the grass roots level if it's ever going to be a force that can compete with the Tea Party. So let's start doing this.
