We seem to have lucked out on this, where we live (a very blue-voting area). There were 2 candidates for the school board seat assigned to our district, and both of them were outside the early voting site when we went. They were both delivering their spiel to us at the same time. One was head of the PTA at a nearby school & the other had actually taught & had some kind of involvement in the DoE during the Obama administration. Both seemed clearly & deeply invested in good outcomes for all involved. As we walked in to go vote, I told my wife that we could probably go either way on that one & still be ok. (The latter candidate won)
ETA:
We got 2 of those flyers, both endorsing the same Dem candidates, except for that school board seat ‐ each flyer went with one or the other. (One was really opaque about who’d sent/paid for it though.)
