Views: Roy style = Node, cannot sorty by votes

(Sorry if this is a duplicate question, but I cannot find it elsewhere in the list of issues.)

Using latest version of Drupal 6 core, Views2, Voting API, and Vote up/down:

I am attempting to use Views to display nodes (using row style = node) with various types of sorting. I'd like to sort the nodes by each node's total # of votes. However, in under the view's Sort Criteria, no vote data is available for sorting. I tried playing around with the relationships, but that doesn't seem to allow me to sort nodes by votes cast.

Thanks for any help.
