In a rare move for a senator running for re-election and a congressman in a safe seat, Wisconsin Sen. Ron Johnson and Rep. Sean P. Duffy, released a joint ad Tuesday, an effort that could help both of their political fortunes. 

The TV and digital spot by the two Republicans will air in Duffy’s 7th District, a vast northern part of the state where Johnson needs to turn out GOP voters in big numbers. Johnson is seeking a second term against Democratic former Sen. Russ Feingold in a tightening race that’s attracted late outside investment from both parties

And the competitive nature of the district and potential drag from the top of the ticket — likely from either Donald Trump or Texas Sen. Ted Cruz — puts this race firmly into play.
