WASHINGTON, Feb 10 (Reuters) - Republican Chris Christie'sU.S. presidential campaign looked to be in trouble on Wednesdayamid news reports he would drop his White House bid and narrowthe field of rivals facing businessman Donald Trump.
A disappointing sixth-place finish in Tuesday's NewHampshire primary raised doubts about the combative New Jerseygovernor's viability as a candidate for the Nov. 8 election.
A spokeswoman for Christie's campaign said no decision hadbeen made about whether he would stay in the race.
Christie's departure would leave eight Republicans vying torepresent the party. Businessman Donald Trump has dominated theRepublican race and won the party primary in New Hampshire on awave of voter anger at traditional U.S. politicians.
U.S. Senator Bernie Sanders of Vermont, a democraticsocialist, swept the Democratic contest in the same state.
The results testified to the sizable share of Americanvoters upset at U.S. economic conditions and willing to send ashockwave to Washington.
Christie had poured much of his campaign's resources intoNew Hampshire and had considered a good showing there critical.
He canceled plans to go to South Carolina, a sign he coulddrop out soon. The state holds the next Republican primary onFeb. 20.
"No decision has been made," Christie spokeswoman Sam Smithwrote in an email to Reuters.
Citing an unidentified source, Politico said Christie wouldsuspend his campaign on Wednesday. ABC News quoted a sourcebriefed on Christie's plans as saying the governor was expectedto formally suspend his presidential campaign as early asWednesday after huddling with advisers.
Trump's opponents could benefit if Christie pulls out.
Ohio's Republican governor, John Kasich, won second place inNew Hampshire, followed by U.S. Senator Ted Cruz of Texas,former Florida Governor Jeb Bush and U.S. Senator Marco Rubio ofFlorida.
On the Democratic side, Sanders courted the African-Americanvote after thrashing former Secretary of State Hillary Clintonin New Hampshire. Civil rights leader Rev. Al Sharpton metSanders for breakfast at a restaurant in New York City's Harlemneighborhood.
