Aidan Milliff and I have been working for years on a project about Indian public opinion toward foreign policy (hopefully someday coming to a scholarly outlet near you!), and part of it involves going through decades worth of historical surveys done by the Indian Institute for Public Opinion.
This is an interesting IIOPO survey on Indian views of the government’s policy toward the 1967 crisis/war in the Middle East in July 1967 among respondents in four metros (Delhi, Kolkata, Chennai, Mumbai), broken down by expressed voting intention. While in most of our work we are not seeing consistent partisan differences in foreign policy views (i.e. in views of the US or USSR/Russia), this is one in which we do see some differences between parties and general ideological inclinations (i.e. compare Swatantra and Jan Sangh to Congress and especially Communists).
