Republican presidential front-runner Donald Trump can beat his Democratic counterpart, former Secretary of State Hillary Clinton, in a head-to-head battle for the US presidency, a new survey revealed.

According to the results of a telephone survey conducted by Rasmussen Reports, 38 percent of American voters chose Trump to be the next US president, making him the top choice in the race to the White House.

Clinton was in close second, gathering the support of 36 percent of the survey respondents.

Five percent, however, admitted that they are undecided at this point on whom to favour in the US presidential race.

The two leading presidential hopefuls also registered more than majority support from voters affiliated with their respective parties.

Trump garnered the support of 65 percent of Republican voters in a possible match-up against Clinton.

The former first lady, meanwhile, got a more sizeable chunk of Democratic voters, 70 percent of whom said they will vote for Clinton.

Also, 78 percent of likely voters who identified themselves as Democrats believe that Clinton will likely be the party's presidential candidate for next year's elections.

Quite interestingly, 24 percent of Republican voters said they would want to see another candidate face off with Clinton, indicating that one in every four GOP voters is not yet sold on Trump as the party's standard-bearer.

Only 14 percent of the Democratic voters said they prefer another candidate over Clinton.

Nevertheless, Trump got the support of 37 percent of those who do not affiliate themselves with either political party, while Clinton received 25 percent of their support.

The same survey also showed that Republican candidate Carly Fiorina will be no match to Clinton if they go head-to-head against each other.

In this situation, Clinton is likely to secure 40 percent of the votes, while Fiorina will only get 34 percent of the votes. Twenty-one percent will favour another candidate, while five percent remain undecided.
