Polls May Be Undercounting Democrats

Nate Cohn: “Polls show that the Republicans have an advantage in the fight for control of the Senate. They lead in enough states to win control, and they have additional opportunities in North Carolina and New Hampshire to make up for potential upsets. As Election Day nears, Democratic hopes increasingly hinge on the possibility that the polls will simply prove wrong.”

“But that possibility is not far-fetched. The polls have generally underestimated Democrats in recent years, and there are reasons to think it could happen again.”
