INDIANAPOLIS (AP) – Indiana politicians are taking to the airwaves in the final weeks of the 2014 campaign season, but their efforts online may be having a bigger impact.

Democratic Secretary of State candidate Beth White and Republican Auditor Suzanne Crouch became the first statewide candidates to go on air with ads this week. Federal Communication Commission records show the pair bought a week of airtime throughout the state.

But Ball State University journalism instructor John Strauss said it's likely that some of the campaigns are also focusing heavily on social media and online interaction.

He noted that White's ad, with its self-deprecating humor, seems geared to a younger audience that would be viewing it online.

It's a far cry from two years ago when campaign ads flooded the airwaves.
