Take the following as truth: Finally, lest their opponents' weakness not suffice to produce a landslide, both incumbents got further help from a third-party  Nixon from George Wallace, who drained white Southern support from the Democrats, and Clinton from Ross Perot, who likely will drain white suburbanites from Dole.
Then the following statement: "Wallace drained 75% of the white Southern support from the liberals." is true, false, or inconclusive?
Answer: Inconclusive
