Democrats have an 8-point lead on a generic congressional ballot heading into the 2018 midterm elections, according to a survey released Wednesday from Public Policy Polling.

The poll from the left-leaning group finds Democrats leading 49 percent to 41 percent on the generic ballot, though that is slightly down from the 51-40 lead they enjoyed in December.

Since the 2016 elections, Democrats have seen a boost in political activity and enthusiasm. The party secured both of the governorships on the ballot in 2017 and flipped a deep-red Senate seat with the election of Sen. Doug Jones in Alabama.
