The US is already divided in half by the Mississippi river. Let's have all the lefties live to the west of the river and all the conservatives east of the river.
On the east side, abortion would be a capital crime. There would be no expensive prison system needed because crime would be punished by financial restitution, flogging, or capital punishment. Everyone above the age of 20 would be required to own a handgun. Islam (a religion that advocates murder) would be illegal. There would be no mandatory health insurance, no social security, no Medicare, no Medicaid, no "free" government indocrina...err...education, no welfare checks, no food stamps, etc. Also, everyone will pay the same percentage of income tax no matter how much they make and those taxes will be below 10%.
The left ...err west coast wouldn't have to even think about building a wall on the Mexican border anymore. They could make any laws they want with absolutely no obstruction from conservatives because there wouldn't be any conservatives. They could have themselves so much fun taxing the hell out of each other!
Question for liberals: Wouldn't that be wonderful?
