Something like this. The White and Minority working class and poor unite behind a common cause economically progressive, socially moderate party. They however still adopt a non interventionist foreign policy.This gives them a good advantage in presidential elections. Though in exchange the Republican Party is able oust trumpism from its party but in order to remain competitive in the Midwest and open up new states to them, they go full McKinley style protectionist while maintaining a Paleoconservative/Libertarian view on civil liberties and foreign policy fully becoming a party of non intervention and isolationism which means both party's don't support interventionism. Anyway they also moderate a little on economic issues due to the increasing focus on economic policy in the nation. These cause a gain in wealthier minority's (meaning something like a 60/55-45/40 support from Hispanics and a 75/70-30/25% support from blacks) and socially liberal folks which causes a increase Republican gain in population heavy states like California which is only lean dem. Though the democrats have a majority, the county is more depolarized and bigger states are closer in margin which makes landslides more likely.
