Using the information in this link 
(http://drupal.stackexchange.com/questions/4559/how-to-alter-country-dropdown-in-location-module) 
I was able to accomplish what I needed done.
I had an existing custom module in which I added this code:

  /**
  * Implements hook_form_alter().
  */
function MyModule_form_alter(&$form, &$form_state, $form_id) {
   if ($form['#id'] == 'views-exposed-form-listing-search-page') {
     $form['#after_build'][] = 'custom_countries_after_build';
   }
}

/**
  * Make changes to countries field after all fields are rendered
  */
function custom_countries_after_build($form_element, &$form_state) {
   $form_element['country']['#options']['NN'] = 'Northern Ireland';
   $form_element['country']['#options']['IE'] = 'Republic of Ireland';
   $form_element['country']['#options']['GB'] = 'Great Britain';
   $form_element['country']['#options']['RU'] = 'Russian Federation';
   $form_element['country']['#options']['CI'] = 'Cote d\' lvoire';
   $form_element['country']['#options']['BA'] = 'Bosnia Herzegovina';
   $form_element['country']['#options']['CD'] = 'Democratic Republic of 
Congo';

   asort($form_element['country']['#options']);

   return $form_element;
}
