I moved 1 hour north of San Francisco about 7 months ago so not even some remote red state. Over a few weeks this summer when I went to Safeway, three people ahead of line (assuming middle class, blue collar workers considering that this mostly the industry here) had their credit cards/debt cards declined, even when trying different cards. One was heartbreaking because he was buying a cake for his daughter's birthday. It definitely underscored how severe the economy is for people and why I thought Trump would likely have a 50%/50% chance of winning.
It is about the economy.
