Liberals in NY and CA wringing their hands about the chances of Trump winning the electoral college could strategically move to states with much smaller margins, instead of running up the vote totals, which does no good at the end of election day. 500k voters spread over just a couple of those states could guarantee a Trump loss. He won in 2016 by something like 50k total votes spread amongst Michigan/Wisconsin/Pennsylvania. It has been done before. Liberals moved west in the 1850s to vote against slavery expanding into the Kansas-Nebraska territories. And that was way before remote work and wifi.

Probably too late for this election cycle, but something I've been thinking about and have only heard one journalist talk about something similar (Charles Blow advocating for black people to move to southern states like Georgia to reclaim majority status and maximize political power). It seems like a relatively simple solution to what many fear is an immediate existential crisis, and much more achievable than a new constitution or new states or constitutional amendment(s).
