She is a madam, but was she his madam?

Eliot Spitzer and Kristin Davis are both prospective candidates for New York City comptroller.

Ms. Davis, a Libertarian who served four months at Rikers Island for running a prostitution ring, claims she once supplied escorts to Mr. Spitzer, a Democrat who resigned as governor in 2008 amid a prostitution scandal.

But Mr. Spitzer has denied that he had any association with Ms. Davis.

This is not your typical comptroller’s race (nor is this your typical campaign fact-check).

In March 2008, The New York Times broke the story that Mr. Spitzer was facing a federal investigation for patronizing a prostitution ring, Emperor’s Club V.I.P. Ms. Davis’s name never surfaced in the paper’s investigation, and federal law enforcement officials have said that her name did not come up in their case.
