These priors of the party in the presidency losing the house and senate really didn't start until the 90's. We also never had a basic right taken away like abortion and a party as extreme as the Republican party. We've been conditioned to assume the Democrats are going to lose the mid terms because they won in 2020 and that's what is suppose to happen. If you looked at polls, voter registration, and actual elections and you would say the momentum is with the Democrats.
