To be fair, Brom had only been in the realm about a week at the time of the election.
Also, the joke candidate was Amaury's wife IG.
Apparently it is very hard to compete against a candidate when he's already won the hearts and minds of the nobles. Too bad Alanna didn't dissappear like a year ago. (for Brom). Then, Brom probably would have won hands down. Oh well.
Winning isn't nearly as interesting as losing...
