Republicans eagerly picked up the Horton issue after Dukakis won the Democratic nomination. In June 1988, Republican candidate George H.W. Bush seized on the Horton case, bringing it up repeatedly in campaign speeches. Bush's campaign manager Lee Atwater said: "By the time we're finished, they're going to wonder whether Willie Horton is Dukakis's running mate."[15]
Campaign staffer James Pinkerton returned with reams of material that Atwater told him to reduce to a 3-by-5-inch (8 cm × 13 cm) index card, telling him, "I'm giving you one thing: You can use both sides of the 3×5 card." Pinkerton discovered the furlough issue by watching the Felt Forum debate. On May 25, 1988, Republican consultants met in Paramus, New Jersey, holding a focus group of "Reagan Democrats" who had voted for Ronald Reagan in 1984.[16] These focus groups convinced Atwater and the other Republican consultants that they should 'go negative' against Dukakis. Further information regarding the furlough came from aide Andrew Card, a Massachusetts native whom President George W. Bush later named as his Chief of Staff.[17]
Over the Fourth of July weekend in 1988, Atwater attended a motorcyclists' convention in Luray, Virginia. Two couples talked about the Horton story featured in the July issue of Reader's Digest. Atwater joined them without mentioning who he was. Later that night, a focus group in Alabama had turned completely against Dukakis when presented with the information about Horton's furlough. Atwater used this occurrence to argue the necessity of pounding Dukakis about the furlough issue.[17]
