Same as homos, libs, feral blacks, and illegals - ALL of them, preferred constituencies of Democrats.
Living in Wisconsin, I have visited the Mall Of America near Minneapolis ONCE, and ONCE was twice too many. There are groups of youth that have attempted to cause some chaos there but so far the police seem to have kept the mall relatively safe. Now that there is more public transportation coming from the inner city of Mpls, things MAY change. I have seen all I care to see of that mall.
