The democrats have the 2022 House race in mind as the closest target, with the 2024 election the main target. They know they will not win in 2020. All the issues they are now pounding will be kept on the front burner the whole time.
By 2024, with almost unlimited immigration, they think the demographics will have shifted permanently in their favor.
They will continue attacking the white demographic.
Until they get the race war they've been fomenting. Then they'll wish they could put that Genie back in the bottle.
