Final Cook Political Report projection picks Democrats to keep House, gain 10 or more seats

Democrats are poised to retain and expand their House majority, The Cook Political Report predicts just a day ahead of the 2020 election.

Cook issued its final House race predictions for the 2020 election on Monday, and all eight of its ratings changes moved in Democrats’ favor. That leaves Democrats safely in expansion territory, with Republicans at high risk of losing twice as many seats as Democrats.

In all, Cook predicts Democrats will add between 10–15 seats to their 34-seat majority, though as few as 5 and as many as 20 could swing. Just eight Democratic House seats are considered tossups with a 50/50 chance of being lost, while 17 Republican and one Independent (formerly Republican) seats are considered tossups.

Cook also predicts Democratic nominee Joe Biden will capture the 270 electoral votes he needs to win the election, while nine Republican Senate seats either lean Democratic or are considered tossups.
