Washington, May 3 (RHC)-- U.S. Republican presidential front-runner Donald Trump is headed for a much-anticipated face-off with Democratic candidate Hillary Clinton in the race for the White House, according to a new poll taking among voters in the U.S.  The CNN poll released on Monday, showed that 84 percent of American voters project Trump as the final Republican nominee in the November election, while 85 percent say the same about Clinton.

However, the inevitability of their nominations has not positively affected the two candidates' support among voters, an area in which Clinton holds a narrow lead over Trump 51 percent to 49 percent.

Other Republican contenders -- Texas Senator Ted Cruz and Ohio Governor John Kasich -- were far behind the New York businessman, winning 25 percent and 19 percent support respectively.

Nearly two-thirds of the participants said Kasich should drop out of the race now that he is no longer able to win the delegates needed to capture the nomination through the primaries and caucuses.  And some 52 percent said the same about Cruz.

Overall, 91 percent of Republican voters said Trump was going to ultimately be the party's nominee.

Donald Trump has expressed concern that the Republican Party might try to "steal" the nomination from him if he fails to win the 1,237 delegates necessary to clinch the nomination.

On the Democratic side, 51 percent of the participants said Clinton was their top choice for the nomination, while 43 percent said they preferred Vermont Senator Bernie Sanders.
