Mr. Hogan’s business mostly involves connecting buyers and sellers in real estate transactions; buying property on spec and selling it later; partnering with builders on commercial and residential real estate; and some direct ownership of developments. It can be lucrative, but it’s pretty plain Jane stuff. Mr. Trump’s business, by contrast, is about promoting his brand — putting his name on everything from apartment towers to mail order steak. He promotes it relentlessly through continual travel to his own golf clubs and other properties in the United States and abroad. In January, Citizens for Ethics and Responsibility in Washington released a report detailing hundreds of potential conflicts of interest, including an uptick in spending at Trump properties by U.S. and foreign government officials and special interest groups since his election. So far as we know, Mr. Hogan isn’t billing taxpayers for weekly travel to golf courses he owns, and foreign dignitaries aren’t clamoring to stay at a hotel he developed.
