Projected race calls are correct 99.9% of the time.
NBC's last two projection errors were 2000 (Bush v Gore presidential race in Florida, which was universally just a fucked race) and 1960.
It is a given at this point that Democrats have, in fact, won control of the House for 2027 (as long as there isn't any Trump shitfuckery, which I think the win this year is going to be way too big for him to even try it).
