It'd be pretty funny if they tried to sabotage his campaign by a series of pranks. Butter the bottom of he shoes so he slips on stage. Put blue hair dye in his shampoo bottle. Itchy powder in his underwear. Links to pornography sites "accidentally" included in press releases. etc.
That would be the perfect plot for a Rob Schneider movie.
The first set of pranks would have to be fumbled such that they end up, by accident, improving Edward's image. "Can't we do anything right?!" Then by the mid-point in the movie they start figuring out how to successfully sabotage him.
Yes - the slipping on stage thing means that an assassin misses him or something, and the attempted assassination raises his credibility (sort of like "they wouldn't try to silence him if he didn't stand for something").
