Forwarding a node URL to a Drupal view

I recently inherited some great work done by folks that allowed Stackoverflow-style Q&A on our Drupal site using this tutorial. We'd like to expand the great work they did by adding in polls as a question type, so that there is a poll that people can respond to, and then they can also provide more in depth answers below. The normal question type works perfectly, but the poll type allows people to do everything except see submitted answers: You can see both examples on our live site now.

I think what's going wrong is that the node being displayed for the Poll is using the actual node page, and not forwarding to /question/[Node ID], which is what happens for the question content type, and which is done by the following module:

<?php
/**
 * @file
 * An example module to redirect the path from a node view for at
 * specific type to a view.
 */

/**
 * Implementation of hook_init().
 */
function example_init() {
  // Using arg() instead of menu_get_item(). Rumor has it menu_get_item
  // can occassionally cause WSOD.
  // We make sure arg(2) is empty so we do not redirect on edit or other
  // node sub pages.
  if (arg(0) == 'node' && is_numeric(arg(1)) && arg(2) == '') {
    $node = node_load(arg(1));
    if ($node->type == 'answer') {
      drupal_goto('question/'. $node->field_answer[0]['nid']);
    }
    elseif ($node->type == 'poll') {
      drupal_goto('question/'. $node->nid);
    }
    elseif ($node->type == 'question') {
      drupal_goto('question/'. $node->nid);
    }
  }
}

Have I screwed up something in the PHP? Do I not know how to do a PHP Ifelse to save my life? Am I barking up the wrong tree entirely? Thanks for any pointers.
