As an activist and scholar, Walters examines black involvement in presidential politics in terms of balance-of-power politics and independent and dependent leverage strategies. Walters believes that in key elections (1960, 1968, 1976), black support has been crucial to the success or failure of Democratic presidential nominees. At the same time, he believes that today ``there appears to be a readiness to adopt more aggressive strategies of electoral participation.'' Ultimately, the goal of black electoral activity ``amounts to addressing the mechanics through which Blacks become part of a more significant political coalitionthe `ruling element' in society.'' A timely and important study for scholars. John R. Sillito, Weber State Coll. Lib., Ogden, Ut .
