my copy of Sussex Electors 1832
states
Votes - the votes cast have been entered afetr the electors name
Cast - using the foloowing numerical code 1 ... 2 ... 3 ...etc.
Notes
Parish of registration is entered in ()brackets whe it is different from that of the parish in which the person resides
entries in Italics did not vote either through death of loss of qualification
Does it have a lot of people who didn't vote? If so it would seem to be an electoral roll that has been annotated to serve as a poll book. From 1832 it was far easier to do this than create a new list for the poll book.
However, if everyone in the list voted then it is a poll book, the equivalent electoral roll would have the names of the non-voters as well.
