Well, we know one group that kept Foley's secret...

WND has this:

"A radical activist on a mission to "out" conservative homosexual lawmakers and Capitol Hill staffers held on to information about Rep. Mark Foley's relationships with underage male pages, suggesting the story would break at the time of mid-term elections.

Blogger Jim Hoft of Gateway Pundit points to a campaign by two activists who had Foley on their "target list" of 20 people and shared the information with the Democratic Congressional Campaign Committee."

More than a year ago, in a March 2005 post, Rogers said he had thought hard about what kind of action to take and said that while none would be taken at the moment, "When we get closer to the mid-term elections, I am sure more will surface."
