Nice, and to move the goal post just a little further, what is the minimum number of people in the minimum number of counties where people from the populous blue cities could move to flip every state blue.

Since electoral college votes are dispersed at a state level, it doesn't matter if those blue votes come from blue counties, so long as they go from a blue state to a red state.
Unless you're talking about the displacement that would be required for every county to be colored blue?
