Republicans have expanded their advantage in the final days of the midterm campaign and now hold an 11-point lead among likely voters on the question of which party should control Congress, a new Wall Street Journal/NBC News/Annenberg survey finds.

Some 52% of likely voters in the survey said they wanted the election to produce a Republican-led Congress, while 41% favored Democratic control.

A week earlier, Republicans had held a narrower, 5-point lead on the question in the Journal/NBC/Annenberg survey.

“The Democrats, who badly need some momentum, find little comfort in these results some ten days out from the election,” said pollster Peter D. Hart, who helped conduct the survey. “The thread holding things together for them is both more slender and now even frayed.”
