Jack Kemp’s role in a pivotal period in American history is at last illuminated in this first-ever biography, which also has lessons for the politics of today. Kemp was the congressional champion of supply-side economics --- the idea that lowering taxes would foster growth. Even today, almost no one advocates a return to a top income tax rate of 70 percent. Kemp didn’t just challenge the Democratic establishment. He also encouraged his fellow Republicans to be growth (not austerity) minded, open their tent to minorities and blue-collar workers, battle poverty and discrimination, and once again become "the party of Lincoln."
