I want to know the answer to the following question:
What year did Chancellor Wrighton submit another bid for a presidential debate at Washington University after 2004?
All the background I'm provided with is that ""These one-of-a-kind events are great experiences for our students, they contribute to a national understanding of important issues, and they allow us to help bring national and international attention to the St. Louis region as one of America's great metropolitan areas," said Wrighton.". Is that enough to answer the question?
Answer: no
