Hello,

How can I parameterize the type of the following data class so that any type can be a Candidate?
  type Candidate = String
  data Poll = Poll [Candidate] [Ballot]

My initial thought was to simply put a type variable in place of Candidate, but that clearly won't work:

  data Poll = Poll [a] [Ballot]
>>  Not in scope: type variable `a'
For context: I am building a voting library that addresses the issue of polarized American politics by implementing the Virtual Round Robin electoral method with a Maximum Majority Voting algorithm for breaking cycles.  The beginnings of the library are available at http://github.com/canadaduane/votelib/blob/master/vote.hs
What is a good approach to the parameterized type issue?  Thank you,
