The movement follows an Oct. 9 update where Cook shifted 18 races in the Democratic direction, projecting a net gain of 9 to 19 seats for the party. Concurrent shifts from Inside Elections downgraded Republican strongholds, including moving Wyoming's at-large seat from 'Solid R' to 'Likely R'. Founder Charlie Cook has previously described a Democratic takeover of the House as a 'done deal' and estimated the party could pick up around 20 seats.
