Bloomberg Prepares Huge TV Blitz, Reserves $30 Million in Ads

Senator Amy Klobuchar of Minnesota, campaigning in New Hampshire, joked that she would also be announcing a multimillion ad buy.

“No, I’m not,” she said, with a laugh. “We are running this in a grass-roots fashion. I’m not going to be able to compete with the money of Bloomberg or Steyer,” referring to Tom Steyer, a billionaire who is also running for the Democratic nomination.

Ms. Klobuchar argued that Mr. Bloomberg’s wealth could turn off some primary voters, who are tired of big money in politics — and the White House.

“I am the opposite of some of these wealthy people running,” she said, recounting a middle class childhood and how she raised all the money to fund her political campaigns. “That’s what people are looking for. They are tired of all the money in our world that’s at the top and I don’t think they want that at the top of our country.”

His ads are slated to run from the early 5 a.m. local newscasts through the late-night shows, and on almost everything in between, including on prime time programming and major sporting events, according to some documents filed with the Federal Communications Commission. In Los Angeles, Mr. Bloomberg was slated to pay $114,000 for four 60-second ads on The Voice, NBC’s popular show.

A spokesman for Mr. Bloomberg declined to comment.

Mr. Bloomberg’s advisers have said his campaign would bypass the first four states that will vote in February — Iowa, New Hampshire, Nevada and South Carolina — and focus instead on Super Tuesday in March and beyond, where his personal fortune would give him an advantage.

A moderate who first ran for mayor as a Republican and then as an independent and is now looking to run for president as a Democrat, Mr. Bloomberg could shake up the 2020 primary by offering an alternative to former Vice President Joseph R. Biden Jr. With voluminous spending, he can crowd the airwaves so much that other campaigns cannot break through.
