Cook Political Report’s final prediction for the composition of the House following the 2020 election should be music to Democrats’ ears.

The nonpartisan publication believes the Democrats, who currently hold a 232-197 majority over Republicans, will expand their margin by 10 to 15 seats. The prediction was announced Monday, a day before Election Day. Its analysis said an increase of anywhere from five to 20 seats for Democrats is not out of the realm of possibilities.
