In the crowded Republican presidential race, Trump with 31 percent was way ahead of Florida Senator Marco Rubio, with 15 percent of prospective Republican primary goers, media said.

Three other candidates Senator Ted Cruz from Texas (13 percent), Ohio Governor John Kasich (11 percent) and former Florida Governor Jeb Bush (10 percent) were running neck-to-neck for the third position.

In the two-way Democratic party race, Sanders (54 percent) has a 14-point advantage over former Secretary of State Hillary Clinton (40 percent).

After Iowa caucuses last week, the primary election in New Hampshire tomorrow is only the second one, and thereafter it would gradually move to other states in then next few months.

Since 1952, New Hampshire primary has been considered a major testing ground for Republican and Democratic nominees. Candidates who perform badly drop out of the race and those who do well become strong contender for their party's nomination.

Unlike other American states, where only registered party members can vote for their candidates, in New Hampshire independents or non-registered peoples have the option to vote in the primary elections of both the parties.

In the Iowa caucuses, which kicked off the presidential election process, Cruz won the Republican race, while Clinton defeated Sanders by a very narrow margin.
