Scandal Brewing in the 9th?
I doubt this will actually become a major issue, if for no other reason I don't know how they would expect Dudley to know. Fair Housing does not require asking if someone is a legal alien, so if a landlord does this, it could result in suits accusing them of discrimination against hispanics. It would be a very bad idea to do this, especially if the people trying to get housing have children. It would open a pandora's box of problems, especially since this is not high income housing ($400/month).
I don't think this will end up becoming a major issue, and I still believe Dudley will keep his seat.
