The latest presidential polls show that Donald Trump's rival Ben Carson has dropped his ratings among Republican voters to a low, that the real estate mogul is now facing a new rival — Ted Cruz.

One poll shows that Trump still maintains his lead, but in others, they reveal that the Texas senator has surpassed him.

In a Georgia poll conducted by Landmark/Rosetta Stone and released on Friday, Trump gets a whopping lead of 43 percent and Carson was seen with a significant drop to a one-digit rating at seven percent, as reported in WSBTV.

Cruz placed second to Trump, with 16 percent of support from Republican voters, followed by Marco Rubio with 11 percent.

Trump may have won Georgia, but three different polls showed that Cruz is already on the lead among Iowa Republicans, Huffington Post shared.

A poll conducted by Bloomberg Politics/DesMoines Register from Dec. 7 to 10 with results released on Saturday revealed that Cruz garnered 31 percent of the support from Iowa Republicans, leapfrogging Trump who is now behind him by ten points (21 percent).

Carson is in third place (13 percent), followed by Rubio (10 percent), and Jeb Bush (six percent).

Meanwhile, the Fox News poll conducted from Dec. 7 to 10 and released on Sunday, showed Cruz and Trump in a two-point difference in rating, with the former having 28 percent support and the latter with 26 percent.

Rubio came in third with 13 percent; while Carson, who led Iowa in October, fell to fourth place with only 10 percent.

Another poll by the Monmouth University conducted from Dec. 3 to 6 with results released on Monday, Dec. 7, also showed Cruz with 24 percent of support from the Iowa Republican voters.

Trump is behind with 19 percent; Rubio with 17 percent; Carson with 13 percent; and Bush and Rand Paul with six and three percent, respectively. Carly Fiorina and John Kasich both received three percent.
