I would agree with you if it was only Texas and a few states, see my other comment on this thread. But given the amount of red territories, I believe we can maintain most of our economic and military might- economic activity of cities are mostly decimated anyway due to poor COVID policies by blue leaders. And again, once these territories are under the control of clean leadership, we'll have much more options in acquiring the few blue territories- negotiation in holding fair elections, taking advantage of their lax voting laws to flood into them when they have elections and changing them from within, in addition to the military option.

Think of it as a purging of the corrupt elements by taking out the good to reduce internal resistance, organizing to clean out corruption from the outside, then reuniting.
