Other similarities would include living in very expensive settings....much has been made of Trump's Tower residence ....but nothing is said about Dolans residence:

"Among archbishops, Cardinal Timothy Dolan of New York leads the pack with this 15,000-square-foot mansion on Madison Avenue, in one of the priciest corridors of Manhattan. Vanderbilt Appraisal Company, a New York firm hired by CNN to estimate the building's value, said it's worth at least $30 million.

AND Dolan is considering downsizing his Chancery (not his home) and Trump IS downsizing his living quarters to move into the White House.
