At the 2016 Democratic National Convention Vice President Joe Biden gave a subtle nod to George R. R. Martin and Dorne in his speech, which starts at the 16:30 mark.
We’ve had candidates before attempted to get elected to appealing to our fears, but they never succeeded, because we do not scare easily. We never bow, we never bend, we never break when confronted with crisis. No, we endure, we overcome and we always, always, always move forward.
I think it was a very nice touch and a testament to GRRM’s tremendous talent and contribution.
