I think they actually are having a parade, scheduled to end at the rally. Convenient for the media. Fox News seems to be enjoying all of this. I notice the ones in Dallas (the rally is being shot pretty close and a shot of a parking lot showed it was pretty damn empty) are waving American flags after the backlash the first time when they all waved their own damn flags.
Those flags will be all over the sidewalk and stuff AFTER the rally.
