Is ACORN handing out enrollment forms at rock concerts any different (ethically) from the behavior of that Southern Christian college (I forget then name) which we discussed elsewhere, of doing everything they could to get their students voting?

Seriously folks, I'm just asking for information, or at least informed opinion. What rules are being broken, how, and by whom?

Down Under, enrollment is compulsory and the Australian Electoral Commission has frequent media campaigns (especially before elections) to encourage people to sign up. They have info at most government offices and do other outreach stuff. It is completely non-partisan.
I think the left-er of our two main parties does sometimes have enrollment encouragement drives since younger voters tend to be left. It's not a big thing. Don't think handing out cigarettes would work too well for their image, though.
