 Days before the U.S. celebrates Independence Day, a Gallup poll finds that just two in five are extremely proud to be Americans. That's the fifth consecutive year that reading has been in the 38 to 43 percent range. The combined share of people who say they are extremely or very proud is 67 percent. That's just four percentage points above the record low in 2020. Five percent of those polled say they are not at all proud. Allison Keys, CBS News, Washington.
