Crass, an ex-Muskie worker (his only apparent credentials), contends that Wallace supporters will be ""the key to future Presidential majorities,"" especially if inflation and unemployment continue. Unlike Greenshaw (see below), he makes an attempt to study Wallace's voter profile, using Gallup and Harris polls to support his claim that Wallace's appeal is spreading ""into every region and population stratum""--though as yet there is little hard evidence that such a trend, conspicuous between '68 and '72, is still gathering momentum. For the most part this is a rather arid and poorly organized survey of voting percentages broken down by region, party affiliation, and, sometimes, ethnic background. Otherwise Crass goes in for some grisly reportage: during a melee between Trotskyists and Klansmen outside Madison Square Garden a woman had her eyeball ripped out. You've heard it all before, and better.
