Food can be shipped from anywhere in the world. Most major ports are in Blue cities
Who are you going to sell your food to without any ports to ship?
While Houston is liberal in the inner city the rest is all red,we'd take over the Port of Houston in short order.
Each year, more than 247 million tons of cargo move through the greater Port of Houston, carried by more than 8,200 vessels and 215,000 barges. The port is consistently ranked 1st in the United States in foreign waterborne tonnage; 1st in U.S. imports; 1st in U.S. export tonnage and 2nd in the U.S. in total tonnage. It is also the nation’s leading breakbulk port, handling 52 percent of project cargo at Gulf Coast ports.
Thats not to mention the 18 other ports in Texas.
But thanks for your concern......
