Got response for polldaddy support. latest update to polldaddy plugin changed from using the post title to the wp_title of the post. So if you are using any seo plugins that alter the page title this would result in the seo optimized version of the page title displaying.
To fix, edit the ratings.php file, line 109:
replace:
$title = apply_filters( ‘wp_title’, $post->post_title );
with:
$title = $post->post_title;
