COMPTON, Calif. — Michael R. Bloomberg’s presidential campaign moved on Tuesday to exploit the chaotic outcome of the Iowa caucuses, escalating an already enormous campaign of television advertising and publicly making the case that a messy outcome in the early states opened the way for Mr. Bloomberg.

Mr. Bloomberg, the former New York City mayor whose campaign is fueled by a multibillion-dollar personal fortune, conferred with advisers on Tuesday morning about the muddled results in Iowa. Encouraged by the murky outcome, Mr. Bloomberg authorized his campaign team to double his spending on television commercials in every market where he is currently advertising and expand his campaign’s field staff to more than two thousand people, strategists involved in the conversations said.

The Bloomberg campaign has been trying to chart an unprecedented route to the Democratic nomination, skipping the first four contests in February but aggressively contesting the array of larger states that begin voting in March. From the outset, Mr. Bloomberg’s advisers believed the strategy would only have a chance of working if another moderate candidate — most likely former Vice President Joseph R. Biden Jr. — failed to emerge from February with a decisive upper hand in the race.

In an interview on Monday in Compton, Calif., Mr. Bloomberg was unusually blunt about his campaign spending strategy and his intent to seek advantages while his rivals toiled in the four early states, which have relatively few delegates needed to win the nomination.
