Con to the question "Was Ronald Reagan a Good President?"
"The core of Reagan's strength had been the public's perception that he was a man of his beliefs: he might compromise on the margins, but he would not sell out his principles wholesale. The shipments of weapons to Khomeini shook the foundations of this belief, squandering Reagan's moral authority...
His was a rhetorical presidency, capable at its best of uniting the country behind a common vision and moving the political center a long step to the right. But the Iran-contra affair revealed his rhetoric to be disconnected from his actions, and his actions to be disconnected from his policies. Ronald Reagan's talents had hidden his flaws too well; inevitably his unmasking was his unmaking."
