It sounds to me like tracking the submission of a vote would work better than tracking the clicking of the link to the page where the vote may or may not be submitted.

If I were going to do something like this, I would create a table that contains two columns, one for userid, and one for the number of votes. And within the script to which the form is submitted, I would include code to update the new table accordingly.

I've already got my hands overflowing with projeccts right now, but does that sound at least in the ballpark of what you are looking for?
