The cost of the Bloomberg campaign for the US elections amounted to one billion dollars

Michael Bloomberg spent nearly $ 1 billion over three months trying to win the nomination of the US Democratic Party to run for the presidency, the Federal Electoral Commission announced on Monday.
Bloomberg, a billionaire and former mayor of New York City, funded his campaign himself and did not accept donations.
Bloomberg left the race in early March after only three months, after disappointing results in the primary.
Bloomberg has spent hundreds of millions of dollars on television advertising, more than any other candidate.
