It appears that was only part of the reason. Another huge issue that affected all of the races was Abele himself, per the Shepherd Express:
An informal exit poll in both districts found that Abele’s strong and visible support was one of the main reasons why many voters rejected each of these candidates. Had these individuals run without Abele’s support and all of his resources, we are not saying that they would have won, because no one can know what would have happened. But according to the sample exit polling, these candidates would definitely have done much better. These two individuals are good people, but they just violated one of the tenets that most mothers tell their children: Be careful who you associate with because there are some people out there who will definitely end up getting you in trouble.What makes this really bad news for Abele is that he is up for reelection in a year and a half. If people are already rejecting him through his candidates, it does not bode well for him.
Sadly, judging by his upcoming 2015 county budget, he hasn't learned the lesson yet and is continuing with his very unpopular agenda of ripping off taxpayers and county workers alike.
