Campaign.
The Democratic campaign was a bruising rematch between 1966 nominee Milton Shapp and Auditor General Bob Casey. As in the prior election, Shapp and Casey proved to be disparate personalities. The liberal and business-oriented Shapp ran an aggressive campaign into which he injected much of his own funding, while the affable Casey ran a relatively conservative campaign and appealed to labor and rural voters.
