To KPY: I thought you had in mind, computer randomizes pattern and prints out the 3 ballot plus 1 copy (it decides which).
That is a disaster since enables trivial vote buying using statistical effects. If same, but YOU decide which to copy, then the scheme still is vulnerable to statistical effects: Example: I support both Clinton and Gore but hate Bush (suppose). I tell you "vote for Clinton and bring me back a ballot-copy that says Clinton=1, Gore=1, and you get a dollar." If you do not vote Clinton but do vote Gore, then your probability of being able to get the dollar, is 2/3. If you do not vote Clinton and do vote Bush, then your probability of being able to get the dollar, is 1/3. If you do vote Clinton, your probability is 2/3. If I do this enough times, I bias the vote a lot. -- Warren D.
