Recent ad attacks by outside groups supporting Democrat Evan Bayh’s Senate bid target the financial offenses of Republican opponent Rep. Todd Young.

Young had several money issues during his time in the House, including taking improper tax deductions on his rental home in Bloomington, Indiana, and bouncing a check when making a payment on delinquent property taxes, The Associated Press reported.

The ads come as Bayh, who previously held the Senate seat for two terms, has himself taken a number of hits in the tossup race, which could determine which party controls the Senate. Recent hits have targeted his post-Senate work with a Washington law and lobbying firm, The Indianapolis Star reported.

He’s also been accused of losing touch with Indiana residents. The ads targeted his old Senate votes that aligned with the financial world from which he was seeking employment before his term even ended.

The pro-Bayh ads criticize Young’s use of more than $500,000 on taxpayer-financed mailers, more than any other Indiana congressional delegate since 2010.
