Businessman Donald Trump and retired neurosurgeon Ben Carson have maintained their lead in the race for the Republican presidential nomination, according to recent polls.
According to a new Washington Post-ABC News poll, released Wednesday, Trump's support remained steady in the past month with 32 percent of Republican primary voters saying they plan to vote for him, slightly down from 33 percent in September.
Carson, meanwhile, has garnered increased support polling at 22 percent from 20 percent previously.
On Monday, a poll released by the Wall Street Journal and NBC News kept Trump in the lead with 25 percent and Carson in second place with 22 percent.
Experts say the polls show that Republican voters are increasingly becoming dissatisfied with "status quo politics" and "politically experienced insiders".
Both polls have Florida Senator Mark Rubio in third place, polling at 10 percent and 13 percent respectively.
The Post-ABC poll has former Florida governor Jeb Bush in fourth place at seven percent, followed by Texas Senator Ted Cuz at six percent, and HP executive Carly Fiorina at five percent.
The Wall Street Journal/NBC poll has Bush at eight percent, Cruz at nine percent and Fiorina at seven percent.
