Sure AIDS is a good cause to contribute money, but Scaife, having received notoriety as the person most responsible for funding a would-be coup against former President Clinton, is damaged goods.
I'd say Clinton should not accept any money from such a source as a matter of principle. To me, what Scaife did was unforgivable:
Ruddy, who accompanied Scaife to the Clinton lunch, says the peacemaking meeting came about after former New York City mayor Ed Koch offered to put the two together. (Koch declined to comment.) Clinton, pouring on the charm, greeted Scaife like an old friend. "President Clinton believes in redemption and moving forward," says spokeswoman Jennifer Hanley. Ruddy says they talked about Clinton's charitable work and avoided opening old wounds. After receiving the full Bill treatment, Scaife left with a new outlook on the man he had once set out to crush. Scaife isn't ready to sign on to Hillary's campaign—he's still a Republican. But his lawyer, Yale Gutnick, says Bill Clinton and Richard Mellon Scaife are now members of a "mutual admiration society." Cue the apocalypse.
