Secession is the talk in California these days. Newsweek Magazine reports that California is California is collecting signatures to put the issue on the ballot. They are calling it Calexit.
I doubt it goes anywhere, but it's an interesting thought exercise. California is a huge place, certainly large enough to be a country. It has an enormous economy. It could continue to trade with the United States and has the harbors and ports to trade with the world.
My first response would be to let them go peacefully. Establish borders. Wish them the best.
The last time some States left the U.S. sent in troops and it was devastating. The casualties accounted for 2.5% of the population. The economic effects in the South are still being felt. Why subject the country to an internal war?
Losing California's reliably Democratic Senators and Congressmen, along California's 54 votes in the Electoral College would be benefit enough. It would ensure Republican victories in the White House and Congress for decades.
And here's why it won't happen.
There is a pipeline that draws water from the Colorado River and diverts it to California. From Parker Dam water is pumped up over four mountain ranges before it flows into California. This pipeline, built as a public works project in the 1930s provides most of the water to Southern California for agricultural and home use.
How much water? Up to 4.4 million acre-feet according to the agreements between the western States and Mexico. An acre-foot of water is 325,851 gallons. 4.4 million acre-feet is on the high side of 97 billion gallons. Most years California doesn't get all of it's allotment, the available water is apportioned by percentages. But even in drought conditions, California's share is 29% of the available water in the Colorado River.
If California seceded, how long would it be before the United States turned off the pumps?
