The Friday File: In addition to US politics becoming increasingly tribal, so is our shopping! While the CNN (Democrats), Fox (Republicans) viewership divide is well known, the NBA is now 50% more popular among Democrats than Republicans. By contrast, NASCAR is twice as popular among Republicans. Other Republican brands include GMC, Chick-fil-A, and Wrangler, which just 15 years ago was a Democratic Brand. Democrats predominantly buy Volkswagens, Levi’s and Starbucks.
