Focus: Democratic Rep. and U.S. Senate candidate Jacky Rosen

Who’s paying for it: Republican U.S. Sen. Dean Heller’s campaign

Size of buy: The Heller campaign did not respond to a question about the size of the buy

When it started: Oct. 26, possibly earlier

Where it’s running: At least Las Vegas; the Heller campaign did not respond to a question about where it is running

The gist: The spot, which largely reiterates a line of attack from previous Heller ads that Rosen has accomplished “nothing” during her first term in the House, features an empty, abandoned office with stacks of papers, empty paper trays and crumpled pieces of paper strewn about, a rat chewing on what appears to be a piece of paper and a voice calling out “Rosen” repeatedly as a phone rings in the background unanswered. Mirroring the imagery, the narrator says that Rosen has done “nothing” in Congress.

“No bills to fix health care. No bills to improve education. No bills to do much of anything. And when our veterans needed her, she skipped a vote to film a campaign commercial,” the narrator says. “Taking care of herself at our expense.”
