Louisiana Gov. Bobby Jindal is making his own play for Republican primary voters who want the GOP to get tough on illegal immigration.

Jindal, an underdog Republican presidential contender, will unveil a web advertisement on Tuesday that features remarks he made during a campaign appearance at the Iowa State Fair. The spot, part of a digital ad buy the Jindal campaign is targeting at potential Iowa caucus-goers, shows Jindal responding to liberal immigration protesters while he was speaking the Des Moines Register sponsored “soap box.”
