Trump rallies

Trump cancelled his rally in Chicago tonight because of concerns about security.  When the cancellation was announced, those at the rally erupted in shouts, scuffles, and violence.  The police did not have a handle on the situation.  There were perhaps a few thousand inside the arena protesting, while the streets outside were lined with police.  It is amazing to see a presidential campaign cause bouts of fights and chaos.  It wouldn't be surprising if eventually someone rushes the stage and attacks Trump.  People are comparing his campaign to George Wallace, who himself was shot.
