Is the registration fee and the raffle from last year tax deductible?

No, any monies paid to entity where yoy receive a benefit or potential benefit in exchange for that $$ is not tax deductible. That is true for any charity.

Who cares? In the perfect socialist state (which America will be in the next 50 years) everyone will be taxed to the hilt…until everyone has the same amount of money. Socialism is on the march people!
