"Meanwhile," Greenberg adds, "budget deficits gave way to surpluses, the economy enjoyed its longest continuous expansion [in history], and poverty rates plummeted."
It's important to disentangle ideology from the questions of success and failure. Unlike basketball, in which success means getting the most points, success to a Democrat – like passing health reform – can mean abysmal failure to a Republican, and vice versa.
The two sides disagree not just on worth but facts. Greenberg, not a Reagan admirer, praises Reagan's greatest second-term achievement – his partnership with Russia's Mikhail Gorbachev to peacefully end the cold war.
" 'Star wars' had nothing to do with it," he says, rebutting the idea that Reagan cowed Gorbachev into submission by pushing a strategic defense shield. "Russia couldn't maintain client states. Reagan was not cynical about Gorbachev. His overtures in the second term revived a hopeful spirit."
Sharply disagreeing about the importance of star wars is Clark Judge, a former speechwriter and aide to both Reagan and George H.W. Bush.
"Yes, the Soviets were [getting] weaker and knew it," says Mr. Judge, now managing director of White House Writers Group, a consulting firm. "Star wars figured into this by making a first-strike capacity obsolete." He describes a variety of early Reagan-era moves strengthening NATO. "All contributed to the realization of how tenuous their position was."
Judge also argues forcefully for other Reagan second-term achievements: "tax reform, holding the line on spending, [supporting] a large number of countries to move from despotism to democracy, and fidelity to judicial restraint."
