Negative political advertisements didn't seem to sway Tennessee voters in several races in Thursday night's election.

The ads did the opposite of what the candidates who put them out wanted them to do.

Negative campaigning included television advertisements and signs. Tennessee voters saw those tactics in big and small races.

"This actually harms the candidates who put out the advertisement and not the target candidate. Citizens see it as nasty. They see it as unnecessary and they don't find it useful for making political decisions,” Dr. Amanda Wintersieck, UTC Assistant Political Science Professor said.

Dr. Wintersieck said the majority of campaign advertising is negative. She's not surprised the candidates who put out the negative ads lost.

While Congresswoman Diane Black and Randy Boyd were busy attacking each other, Bill Lee secured the GOP nomination for governor.

"He slipped through this because you have six candidates. One relatively unknown, Bill Lee, and then these four others who are fighting it out in a way that's having a boomerang effect on each of those and somehow in the midst of that, Bill Lee is able to slip through the cracks unharmed,” Dr. Wintersieck said.

The State Representative District 30 race also saw some mudslinging.

Signs that said Esther Helton voted twice for President Obama were seen around parts of Chattanooga.

Helton beat Jonathan Mason by 140 votes for the Republican nomination.

Dr. Wintersieck said both races teach an important lesson.

"I don't think that it's safe to assume that because the state went heavily for Donald Trump that taking on Trump-esque tactics in this election are going to be an effective method given the political history of Tennessee,” Dr. Wintersieck said.

Dr. Wintersieck said Tennessee is known to bounce back and forth with electing candidates from both parties.

Republican Bill Haslam is finishing his second term. Before him, Democrat Phil Bredesen served two terms.

Wintersieck said a moderate campaign approach is likely best when communicating with Tennessee voters.

She also believes the gubernatorial race will be one of the most expensive in state history.
