Votes were still being tallied and key races remained uncalled as Election Day came to an end. But as of 1 a.m. ET on Wednesday, when the last polls closed in Alaska, Democrats were projected to gain more than three dozen seats in the House and as many as nine seats in the Senate — far beyond the three and four seats, respectively, that they needed to retake each chamber. They were also on track to win the majority of governorships for the first time since 2011.
