Trump has captured Americans interest with his straight-forward conversation about illegal immigrants and unfair trade agreements with foreign nations. He now enjoys 28 percent support among registered voters nationwide, up from 20 percent according to a July 30 survey by Quinnipiac University.

His lead shows the widest margin to date for any Republican in the election cycle, according to the survey.

Retired surgeon Ben Carson came in second with 12 percent, followed by former Floridagovernor Jeb Bush, Senator Ted Cruz and Senator Marco Rubio, each with seven percent.

Wisconsin Governor Scott Walker surveyed at six percent, and Ohio Governor John Kasich and businesswoman Carly Fiorina each registered five percent.
