Traveling in California and New York over the last couple of weeks, I noticed something in the summer landscape of these two deeply blue states that is more reminiscent of rural America this time of year – a surfeit of American flags.

It’s not unusual to see a flag in liberal provinces, of course. But in the Bush years of sanctioned torture and war built on deceit, many Americans withdrew from overt displays of patriotism. Some said they were ashamed of their country.
