Back in January, when Newt Gingrich was still a GOP hopeful, he presented the idea of making the moon into the 51st member of the United States. Fast-forward a few months: Gingrich did not win the nomination, the moon remains uncolonized, but the notion of another state was in fact a very real part of the 2012 election. In Puerto Rico, a clear majority of citizens voted for the island’s statehood.
This doesn’t mean that Puerto Rico will be promptly admitted to the union. A number of factors and decisions still stand between the vote and the final outcome. However, it does beg the question: What would a 51-star flag look like? And, for that matter, what was the design process at other moments in history when the US scaled up its territory?
