This is what I gleaned from the Kerry blog:
it's old "news", since it's obviously just made up. It probably goes back to a relation John Kerry had BEFORE he married Teresa Heinz. Here's the report from NewsMax the Drudge report obviously is referring to:
"Brinkley to Imus: Kerry's Private Life Won't Be an Issue
Presidential historian Douglas Brinkley said Thursday that reports indicating that John Kerry's first marriage to heiress Julia Thorne had collapsed amidst allegations of infidelity should not become an issue in this year's presidential campaign.
"After his separation and before his marriage [to heiress Teresa Heinz], he was single, so stories might emerge from that era, but I don't think that will cause him any trouble," Brinkley told radio host Don Imus.
Brinkley's recent book, "Tour of Duty," offers what critics say is a whitewash of Kerry's exploits with the controversial group Vietnam Veterans Against the War after Kerry left the military. Brinkley's book also offers a very favorable portrayal of the highly decorated Kerry's Vietnam combat experiences.
The London Times suggested last weekend that Kerry may have had a relationship with a female law partner before he divorced Thorne, though Kerry was separated from his wife at that time.
"He separated from his first wife Julia Thorne in 1982, though the divorce was not finalised until 1988," the Times said.
Before his marriage to Heinz, Kerry was considered one of the most eligible bachelors in the Senate. With his divorce proceedings under way, the Boston Globe called him "The Senate's New Romeo," as the senator kept a high-profile romantic life. "
It's also rumored to be a strike by Bush because Kerry has the GWB abortion story.
