Four in 10 Americans are backing the real estate mogul's campaign after his victory in the New Hampshire primary last Tuesday, according to a Morning Consult survey released Friday.

Trump earns 44 percent support from registered Republican and Republican-leaning independent voters. Sen. Ted Cruz (Texas) comes in a distant second, with 17 percent.

Retired neurosurgeon Ben Carson and Sen. Marco Rubio (Fla.) are in third, with 10 percent each.

Trailing them are former Florida Gov. Jeb Bush, with 8 percent, and Ohio Gov. John Kasich, with 4 percent.

Six percent "don't know" or have "no opinion" on which GOP candidate they support; 1 percent prefer "someone else."

Trump is also viewed favorably by more than 6 in 10 of his party's voters, pollsters found. He has a 67 percent favorability rating; Rubio's is 62 percent, and Cruz's is 61 percent.

Friday's results found that Trump's support has risen 6 points since his win in New Hampshire.

Trump earned 38 percent before Tuesday night's vote. Cruz's 17 percent remains unchanged since Morning Consult's last poll, and  Rubio is down 5 points.

Morning Consult conducted its latest poll of 710 Republican and Republican-leaning independent voters nationwide Feb. 10-11. It has a 3.7 percentage point margin of error.
