It's like the apocryphal quote about Nixon by Pauline Kael (which she didn't actually say): “I can’t believe Nixon won. I don’t know anyone who voted for him." Kael was a New York film critic, so the joke here is that in the urban intelligentsia, she and her friends were not Nixon fans. But of course, that circle in New York City does not represent a giant country like the US, nor would upper class liberals in Tehran represent a country that was primarily peasant farmers and villagers, who were conservative and religious.

A plurality of the people did support Kohmeini, although they didn't necessarily know what he would implement. Some of the first things they did when coming to power was crack down on those who would oppose them (a good revolutionary always consolidates the revolution...), which ended up being a lot of people involved in getting rid of the Shah. Revolutions tend to devour their children...

The actual quote was " ‘I live in a rather special world. I only know one person who voted for Nixon. Where they are I don’t know. They’re outside my ken. But sometimes when I’m in a theater I can feel them.” Which certainly shows a self-awareness about her circle.
