I think the only important part of the URL is the ID number at the end. So, no matter what the username is changed to, as long as you have that unique numeric ID, it will go to the correct place. You can check this by changing the "POTUS" string to anything else you like, and sending your browser to that modified URL:
Does twitter use the JSON api? AKA doesn't that url only have the username/status part for "discoverability" reasons, but realistically that tweet id at the end is the ACTUAL id for the tweet?
