Embattled Republican U.S. Senate candidate Roy Moore led his Democratic opponent by 6 percentage points in a CBS News poll released on Sunday, with most Alabama Republicans saying the allegations of sexual misconduct against him are false.

Moore was leading Democrat Doug Jones 49 to 43 percent among voters likely to cast ballots in the Dec. 12 special election, CBS said. The contest was even among registered voters, it said.

Republican lawmakers in Washington, including Senate Republican leader Mitch McConnell, have distanced themselves from Moore and called for him to step down from the race after he was accused by several women of sexual assault and misconduct when they were teenagers and he was in his early 30s. Reuters has not been able to independently verify the allegations.
