Fracking was outlawed in Blue America; Red America became the world’s number one petroleum exporter. Blue America laws banning nuclear and coal power led to the “Kentucky Line” of coal plants running parallel the state’s northern border with Blue Ohio, selling Blue America the power it refused to generate itself. The ban on GMO crops and many pesticides cratered Blue American food production, a void Red American farmers were happy to fill. All the while, Denver, Dallas, Atlanta and other cities grew their own tech and entertainment industries built on refugees from Silicon Valley and Hollywood looking for an environment where success was not penalized. Red America began to supply itself with what Blue America used to provide. Blue America’s deficit exploded even as Red America balanced its budget, per the one new amendment it had added to the Constitution.
