No way to customize poll_page

The output of poll_pages() is very simple:

  $output = '<ul>';
  foreach ($queried_nodes as $node) {
    $output .= '<li>' . l($node->title, "node/$node->nid") . /*' - ' . format_plural($node->votes, '1 vote', '@count votes') .*/ ' - ' . ($node->active ? 
t('open') : t('closed')) . '</li>';
  }
  $output .= '</ul>';
  $output .= theme('pager');
  return $output;

Unfortunately there's no easy way to customize the individual line display, so e.g. if you want to remove the actual vote counts there's no easy way without leaving two dashes floating in between the title & active status.
