The Dems winning the house was ALL-important. I can't tell you the emotions I felt when the results on election night were becoming clear. The fear I wasn't allowing myself to feel before the results were clear had to be felt somewhat in order to feel the relief of having won the House.
The other thing it said is, in contrast to learning all the horrible realities about Trump supporters, we learned that there are even more (roughly) Americans who still understand what American democracy means (independent judiciary, free press, moral leadership from the president, etc.). Winning the House was no less heartening for its absolute necessity.
