Hillary Clinton outspent Bernie Sanders over the airwaves in Kentucky, which holds its Democratic presidential primary on Tuesday, according to ad-spending data from SMG Delta.
Clinton's campaign spent $178,000 in ads in the Bluegrass State, while Sanders spent $107,000.
That's a reversal from past Democratic contests -- in New York, Pennsylvania and Indiana -- where Sanders enjoyed the advertising advantage.
In Oregon, which also holds its primary this Tuesday, Sanders spent $123,000 over the airwaves, although it was a limited cable buy. Clinton didn't spend a dime in the state.
