3. Democrats won the House with the largest midterms margin ever

Democrats took control of the House this year with the largest midterms margin of victory in history, surpassing the previous record of 8.7 million votes in 1974, according to NBC News election data.

By the numbers: Democratic House candidates currently have an 8,805,130 vote lead over Republicans, gaining 53.1% of the more than 111 million votes cast nationwide compared to the GOP's 45.2%, according to the data. The House flipped 41 seats during the 2018 election cycle, and could flip another if California Democratic candidate T.J. Cox, who has overtaken Republican incumbent David Valadao, ultimately wins the state's 21st district.

Editor's Note: This article has been corrected to note that this is the largest margin in a midterm election (not that it was the largest margin ever).
