Christie ends 2016 White House bid

New Jersey Gov. Chris Christie has ended his campaign for the Republican nomination for president after a disappointing sixth-place finish in New Hampshire's primary.

Christie on Tuesday night told supporters he was heading home to New Jersey to "take a deep breath," await the final tally of results and decide what to do next. He said he was leaving New Hampshire "without an ounce of regret."

Carly Fiorina announced on social media that she too was dropping out. The former chief executive of Hewlett-Packard won just 4 percent of the vote in New Hampshire. Christie had 7 percent.

Christie had been banking on a strong finish in New Hampshire and spent more than 70 days campaigning in the state, holding well-received town halls and meet-and-greets.

But Tuesday's result appeared to be the final blow for a candidate whose campaign, at points, saw glimmers of hope, but had trouble from the get-go raising money and building support in a crowded Republican field dominated by another brash East Coaster, businessman Donald Trump.

While Trump has posed a challenge to the entire Republican field, his dominance seemed especially damaging to Christie, who had branded himself the "telling it like it is" candidate.

He'll return home to finish his second term as governor of New Jersey, where he faces a slew of unsolved problems and rock-bottom approval ratings from residents who, polls show, feel he neglected the state to pursue his national ambitions.
