Trailing by double digits in some recent polls, Indiana Senate candidate Brad Ellsworth (R) is going on offense against Republican rival Dan Coats.

Ellsworth's new TV ad says Coats "sold out" Indiana by becoming a lobbyist and supporting trade deals like the North American Free Trade Agreement.

"During his 18 years in Congress, Dan Coats voted for trade agreements like NAFTA that made exporting American jobs a way of life," the announcer says in the ad. "Then Dan Coats made millions as a Washington lobbyists while his firm was helping corporations ship jobs overseas. Coats’ firm even trained corporate executives on how to fire American workers."

A spokeswoman for Ellsworth did not respond to a question about where the ad is airing in the state.
