COLUMBUS, Ohio — Sen. Rob Portman is touting his efforts to tackle heroin addiction in the first statewide television ads of his 2016 re-election campaign.

The three 30-second spots were released Tuesday. They begin airing Wednesday.

Portman uses the advertisements to tout a Senate-passed bill aimed at issues including prevention, treatment and law enforcement help of which he was the chief sponsor.

He doesn’t mention Democratic former Gov. Ted Strickland, who seeks to unseat Portman this fall. Strickland is viewed as among Democrats’ best hopes nationally to take a seat in the Republican-led Senate.

Portman’s campaign has bought $14 million in TV time from Wednesday through Election Day in 10 Ohio markets. Portman has significantly outraised Strickland on the campaign side, but outside groups are spending millions for and against both candidates.
