We can start off with a link over to Zorro who is probably talking with tongue in cheek HERE. More than few politicians (current and former) have been falsely accused of being under investigation and Susie was the one hammering that accusation home... so it's kind of funny to see the table turned.
I often write about how some actions "look bad." Which is different than "is bad." What seems wrong isn't always actually illegal. Susie's actions as campaign manager while sitting on the EPISD look bad... but nobody has proven that anything unlawful has taken place.
Voters are left with a bad taste in their mouth when they witness political incest such as you have here. At a minimum the vertical integration of power makes them nervous. They feel they've been cut out of the decision making process. At its worst you have pay to play fires burning all around town and it takes outside law enforcement to put them all out.
No body of elected officials in town should give voters the impression that they are asking vendors to provide political support in exchange for contracts. I'm not saying that's happened here, but it doesn't take much of leap to get there in a voter's mind.
If your day job is campaigns, maybe you shouldn't be serving in an elected office? No matter how well you separate the two, there will always be questions.
