And on the other side you have inflation, gas prices, trans stuff, and critical race theory stuff all working against the Dems, Incumbant Democratic president having around 43-45% approval rating, incumbant party often losing seats in the midterms, generic House polls still showing the Dems losing seats, and the polls having underpredicted Republican turnout in 3 straight elections because Trump supporters just plain don't answer pollsters and that doesn't seem to ever get factored in.
I'll agree some recent developments have been encouraging. But "encouraging" means reducing a 60-seat bloodbath to just a 20 seat loss. The pundits have been wrong plenty of times before, but it was striking to me that literally every person they talked to on NPR said that they expected the Republicans to win the House.
Checking FiveThirtyEight, they have the polls still favoring Republicans too:

74% chance of Republican victory, 26% chance of Democratic victory. So there's a real shot for Dems, but they're pretty far behind still.
