And those Washington billionaires founded some of the most famous companies in America: Amazon, Costco, Microsoft, Nordstrom and Starbucks are some you might encounter on any given day. Massachusetts-based companies like Staples, Raytheon, EMC and Boston Scientific are certainly heavy hitters, but just don't pack the same punch.
Massachusetts is a much older state, and had a big jump on Washington for generations, but now it seems like the land of the Seahawks is catching up quickly. People are literally moving out of New England (though its population is still growing) and toward more moderate climates like Washington and its neighboring states. So even though Massachusetts has the better economy right now, Washington could pass it.
To be sure, the fan bases for both teams expand far beyond those individual states. According to Facebook data, Seahawks fans are still dominant in nearby states like Oregon, Idaho and Montana. And as their name implies, the Patriots are the team for all of New England. Most of Connecticut roots for the Pats, along with the entirety of Rhode Island, Vermont, New Hampshire and Maine.
