Michael Bloomberg set to spend more in one week on TV ad blitz than any candidate ever

Michael Bloomberg will spend tens of millions of dollars on television ads, which would set a record, in at least 100 media markets across the country starting next week, a sign that he could announce his presidential campaign in the coming days.

The ads, some of which are 60 seconds long, are expected to air from Nov. 25 through Dec. 3. They are expected to cost Bloomberg at least $30 million, the New York Times and ABC reported. The sum is more than half of the about $50 million all the other Democratic presidential candidates combined have spent on television ads this year, according to FiveThirtyEight.
