Trump commands a 15-point edge over his nearest competition in the NBC News/Survey Monkey poll released Tuesday.

He receives 35 percent, topping Sen.

Marco RubioMarco RubioSenators introduce new Iran sanctions Senate intel panel has not seen Nunes surveillance documents: lawmakers With no emerging leaders, no clear message, Democrats flounder MORE (R-Fla.) at 17 percent.

Retired neurosurgeon Ben Carson is fourth with 7 percent, while a three-way tie exists for fifth place nationwide.

Former Gov. Jeb Bush (R-Fla.) is deadlocked with Govs. Chris Christie (R-N.J.) and John Kasich (R-Ohio) at 3 percent apiece. Former Hewlett-Packard CEO Carly Fiorina rounds out the GOP field with 2 percent of her own.

Tuesday’s results, however, also found less confidence that Trump will win the Republican nomination.

About 42 percent believe he will take that honor, pollsters found, but that result is down 20 points from last week.

Another 31 percent predict Cruz is getting the party’s nod, while 18 percent say the same about Rubio. Both men have seen 10-point bumps in that category since Iowa’s first-in-the-nation caucuses earlier this month.

NBC News/Survey Monkey conducted its latest sampling of 2,887 registered Republican voters nationwide via online interviews from Feb. 1-7. It has a 2.7 percent margin of error.
