Former New York City Mayor Michael Bloomberg announced on Monday that he will not mount a presidential run this year, saying he doesn’t want to pave the way for Donald Trump or Ted Cruz to win the White House.
Bloomberg’s decision to back away from an independent bid is a relief for Democratic front-runner Hillary Clinton, who could have seen support bleed over to Bloomberg in a three-way race.
In an editorial he posted on Monday, Bloomberg said that if he had run, it was unlikely that any candidate would win a majority of electoral votes and that the responsibility of choosing the next president would be kicked to Congress.
