Are donations to charity contests tax deductible?

Well, its tax time. And while I am going through everything I was wondering about this. I donated $100 for the Wrigley EB charity contest and also donated for a similar contest for another band. Didn't win either. But wondering if these are tax deductible? Thanks in advance.
