American public opinion toward the space program

From Alexis Madrigal, this was news to me:

In thinking about the recent battles over NASA's budget, it seems like the problem is simply citizen support. People don't care that much about space, so space doesn't get funded. Back in the Apollo days, people loved the space program! Except, as this Space Policy paper pointed out, they didn't. A majority of Americans opposed the government funding human trips to the moon both before (July 1967) and after (April 1970) Neil Armstrong took a giant leap for mankind. It was only in the months surrounding Apollo 11 that support for funding the program ever reached above 50 percent.
