Odd thing about that "Hip-Hop Voter Registration Rally": the Boston Public Schools blog mentioned the event, which, at the time, made me think that it was an officially-sanctioned event by either the city or BPS. In retrospect, my instincts were probably wrong, but I also wonder if city agencies/employees would still publicize the event if they knew in advance what might happen at it.

I don't know what was going on at this particular event.

The worst kind of registration drive I've heard of is when it's run by a partisan organization that quietly discards the registrations that would likely favor the opposition.

This is called "politics" and "free speech," nothing illegal going on. Many campaigns have voter registration drives attached to them.

It was a voter registration event and it sounds like people are trying to make a connection simply because it was hip hop and the Senator is African American. All it takes at this point is a mention of the Senator's name anywhere and some people get angry. If people were that concerned about the event, why didnt they volunteer to help out? There appears to be more to this situation than simply uneasiness. If people know how to use a sticker, does that mean some harm has been done? Is that subversive in some way? Professionally, not in one article have I read she has done something wrong in the Senate. Your argument regarding her "discretions" is tired and old. It will not sway her supporters.
