The outsourcing of American jobs — along with allegations of having done so — has become a common refrain in the Indiana Senate race.

The latest paid communication on the issue comes from Senate Majority PAC. The Democratic super PAC is debuting two statewide TV ads on Tuesday — one positive spot about incumbent Sen. Joe Donnelly and one negative ad attacking the GOP nominee, former state Rep. Mike Braun. The ads, obtained first by Roll Call, are backed by a $450,000 buy.

The negative ad opens by poking fun at Braun’s now-infamous blue shirt, which he wore to a GOP primary debate earlier this year. It quickly became his way of distinguishing himself from his opponents.

“Mike Braun and his blue shirt. Pretending he’s the All-American guy,” the narrator says. “Well, over the last two years, Braun made nearly $20 million dollars.”

“And a big chunk of that came from outsourcing,” the narrator continues.
