I have been doing original research into the American media and public reaction to ping-pong diplomacy for the past few months for a history workshop course at my university. One of my main sources for gauging public reaction and how ping-pong diplomacy affected the attitude of Americans towards the PRC was public opinion polling. Up until this afternoon, I had not come across any other scholarly that used this public opinion polling in the context of the public's reaction to ping-pong diplomacy, but it had been used in other academic work as a barometer for the American public's attitude towards Communist China. I have other sources for looking at the public's reaction, such as letters to the editor and some contemporaneous interviews of members of the public, but I want to have another type of primary source to gauge the reaction of the American public. Would y'all have any suggestions?
