The Michigan Model, Professor Michael Marsh
This is classically presented in A. Cambell et al The American Voter, which is available via Google online. Critical chapters are 2, 6 and 7. Or look at a redced version, for instance in R. Niemi and H. Weisberg eds, Classics in Electoral Behaviour ch 22 [based on TAV ch 6-7].
A sympathetic but contemporary restatement is M. Lewis-Beck at al, The American Voter Revisited ch 6-7.
