Democrats held an 8-point advantage among likely voters in the contest for control of Congress, according to the latest PBS News/NPR/Marist poll released with one week remaining before Election Day. The poll indicated Democrats had significant advantages going into the election.
NPR reported that weaker enthusiasm among some key groups could limit the scale of Democratic gains. Pollster Nate Silver said polling would need to be substantially off for Republicans to retain control of the House, citing Democratic primary turnout and early-voting data. The reports did not provide additional poll methodology or vote totals.
