During the midterms, Indiana politics will have everything anyone could ever want: a competitive Senate race, colorful candidates, and now a complete Mariachi band.

That last addition comes courtesy of the National Republican Senate Committee, who sent the authentic five-man troupe to troll incumbent Sen. Joe Donnelly, D-Ind., during a recent campaign stop. As far as political gimmicks go, this one wasn't half bad.

Donnelly has been dubbed "Mexico Joe" for condemning outsourcing publicly while his family business sent jobs south of the Rio Grande privately. Even after selling his shares in the company, Donnelly has been battling back charges of hypocrisy. Now he will have a Spanish soundtrack.

"Joe Donnelly can try to make Hoosiers forget about his family business's outsourcing controversy," an NRSC spokesman promised in a press release, "but we'll make sure it's the first thing on voters' minds when they head to the polls in 2018."

And that might work. Indiana remains one of the heaviest manufacturing states in the country and voters in Fort Wayne and Woodburn don't take kindly to outsourcing. Regardless, that election is a long way away and, to his credit, Donnelly took the Mariachi band in stride with a smile.
