Going onto the Joe Biden website, it's currently asking for donations for his presidential election campaign and potential legal action. Some of the options seem to be quite random though:
For those who can't see the image, the options are $15, $32, $50, $100, $250, $500, $2800, and OTHER.
Most of these are nice round numbers which is understandable. Looking at this question, the $2800 is due to being the maximum contribution that an individual can make. But why $32? Is there a reason for this not being a round number like the rest?
