Donald Trump's stumble in Iowa has apparently deflated his lead in the GOP presidential race in Georgia, but on the Democratic side, Hillary Clinton maintains a domineering lead over Bernie Sanders, a Landmark Communications/RosettaStone poll commissioned by Channel 2 Action News shows.

Trump drew 43 percent support in a December poll, but has fallen to a more assailable 27.3 percent, likely a result of his second-place finish in Iowa on Monday.

Clinton dominates Sanders 63.3 percent to 21.5 percent, according to the poll of 600 likely Democratic voters. She maintains the support of 77 percent of African-American voters polled. See the crosstabs here.

Vying for second place in the Republican field are the two Cuban-Americans, U.S. Sens. Ted Cruz of Texas (18.3 percent) and Marco Rubio of Florida (18.2 percent). Cruz was at 16.2 percent in December, but Rubio has shown significant improvement from his 10.6 percent showing as 2015 closed.

Former Florida Gov. Jeb Bush, who has drawn so much cash out of Georgia, registers far behind at 3 percent in the current poll, down from 4.8 percent in December. The crosstabs can be found here. The overall (MOE of 4.4 percent) on the Republican side:

Ted Cruz: 18.3 percent;

Marco Rubio: 18.2 percent;

Undecided: 15.4 percent;

Ben Carson: 7.7 percent;

John Kasich: 4.4 percent;

Chris Christie: 3.9 percent;

Jeb Bush: 3 percent;

Carly Fiorina: 1.8 percent.
