Text: (One of the many comic-opera touches in the late unlamented Dole campaign was the constant struggle between Jack Kemp, who tried incessantly to give Wanniski a key role, and the sensible economists who tried to keep him out.)
Entailment: Jack Kemp wanted Wanniski to play a key role, even though sensible economists didn't agree.
Contradiction: Most of the sensible economists were in agreement with Kemp that Wanniski should have a key role.
