Democrats hold a 13-point lead over Republicans among likely voters on a generic congressional ballot, according to a new poll.

The CNN survey, which was conducted by SSRS and released on Monday, revealed that 55 percent of likely voters favor the Democratic candidate while 42 percent of likely voters prefer the GOP candidate.

The Democrats' lead is similar to the one they held in a CNN poll released on Oct. 9. It found that 54 percent of likely voters surveyed favored a Democratic congressional candidate in their district. Forty-one percent of likely voters, meanwhile, said they preferred a Republican candidate.
