Generic Ballot Lead Comes Mostly from Strongholds

“Democrats lead by 14 points among likely voters in the latest ABC News/Washington Post poll, a result reported previously. But that reflects a vast 38-point Democratic lead in districts already held by Democratic members of Congress. In districts the Republican Party holds, by contrast, it’s a tight 45% to 51% Democratic vs. Republican contest.”

“The Democrats’ lead in their districts, 64% to 26%, marks the extent of potential Democratic overvoting in areas where they’re already in control – which partly reflects a Democratic concentration in urban areas, and possibly also gerrymandering of district lines.”
