Really? You're going to end the corrupting influence of corporate money in politics by out-fundraising them?
Having money is the one thing corporations are good at, and they're really, really good at it. If your strategy hinges on using money as influence, you're always going to lose, because they are FAR better and more practiced at that game than you are.
The only way to advance this particular agenda is to exploit the strengths that we have which corporations don't. We can fill the streets with real people, we can make disruptive spectacles and speak earnestly about social problems. Unlike corporations, we don't need to hide behind spokespeople and PACs, because we have authenticity. We are genuinely concerned about the future of our democracy, and though corporations can try hard to simulate that concern, it's never as authentic as the real thing.
The MAYDAY PAC is like David trying to beat Goliath in a fist fight. Don't fight on his terms, use the sling, idiot!
