[Q]: Sentence 1: A run by Mr. Feinblatt would complicate what is already a three-person race because he most likely would have the support of the powerful mayor, who is running for a third term. Such a move could also irritate the outgoing district attorney, Robert M. Morgenthau, because it could hurt the chances of his preferred candidate, Cyrus R. Vance Jr. The relationship between Mr. Morgenthau and Mr. Bloomberg has been strained, in part because of the district attorney's investigation into the fire at the former Deutsche Bank building, which found that lapses by the city had contributed to the deaths of two firefighters. Sentence 2: Feinblatt works for Bloomberg.
