OK, maybe not all of them, because it does really seem that there’s a new entrant every day. Nevertheless, MarketWatch, with the help of Zillow, has put together a photo gallery and summary of at least 15 of them. Highlights include the Clinton’s four-bedroom, six-bathroom house in D.C., estimated at a current market value of $5.76 million, and Jeb Bush’s flat, valued at only $1.1 million — which seems a little low for a Bush residence to us. We’ll leave it to your imagination who has the largest current mortgage.
