US 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, a new national poll has found.

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

Interestingly, 43 percent of non-Trump voters said if their candidate fails to win the nomination they will back the real-estate mogul�s candidacy instead.

At 39 percent, more voters said they were enthusiastic about a Trump nomination, while 21 percent said the same about Cruz and 13 percent felt so about Kasich.

About 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. 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.

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.

According to an Associated Press count, Trump has 996 delegates compared to Cruz�s 565 and Kasich�s 153.

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.

Forty-one percent of the voters said they were enthusiastic about the former First Lady and secretary of state�s nomination.

In terms of delegates count, Clinton has so far won 2,165 delegates of the 2,383 delegates required for nomination while Sanders is far behind by winning only 1,318.
