What Do These People Hope To Prove - Really?

Close to 10,000 supporters of Ron Paul are converging on Minneapolis to hold "Ronstock '08" - an alternative to the Republican convention. What's the point, other than the official talking points from the organizers? Isn't it a waste of time and money? Paul couldn't even get the Libertarian Party nomination. At least they aren't planning on disrupting the regular convention, but why bother? No one is going to listen to them, and you can bet there will be no media coverage, unless Comedy Central decides to show up.
