If you have the spoons, start priming friends and family NOW: ensure they're registered to vote, understand the positions/stakes, vote socialist-Democrat in primaries, and for propositions that promote voting access.

If they're more conservative, it's best to focus (truthfully) on how Trump and the Republicans are selling America to the rich. Raising the minimum wage & higher wealth taxes work best as arguments dovetailed with their blatant corruption and self-serving platforms.
