It says as follows:
"Also referred to as a congressman or congresswoman, each representative is elected to a two-year term serving the people of a specific congressional district."
Delegates are elected Representatives but not elected by people in one of the 50 United States.
Our Congressional House of Representatives, paid for by our tax dollars, calls them all congressman or congresswoman.
Like it or not, Congress calls them that. Further discussion is pointless.

Close, but no cigar - however, you do get props for trying ...
The operative phrase is "specific congressional district" ...
If you check the ABC, CBS, CNN, NBC, Polidata, or any other trustworthy web site - you will find that Washington DC and the territories are EXCLUDED from "congressional districts". That is because they are at-large districts with NO CONGRESSIONAL REPRESENTATION ...
Now, I am using your OWN quote against you - so you can't say that I didn't play fair ...
But you DID make a good attempt at bootstrapping your way through the back door ...
I've demonstrated that the US House of representatives does just that. Whether it is legal in every sense is irrelevant. If Congress want to call then Sugar Plum Fairies they can do that too.
If Congress self identifies it's attendees by a certain name, that has to be good enough for all of us. I'll have that cigar now.
