Basically what it says on the title. Could someone from DC or from one of the US territories (Puerto Rico, Guam, Mariana Islands), legally run for president?
And who would be a good candidate from a territory or DC, for each party? And would they have a shot at winning if they did run?
DC yes, the territories no.
Territories yes, except for American Samoa. Residents of the territories are natural-born citizens.
I doubt they'd gain any traction, however, since they are barely known outside their home territories. Puerto Rico being the only exception.
