The definition of racism, from dictionary.com:

1. a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one’s own race is superior and has the right to rule others.
2. a policy, system of government, etc., based upon or fostering such a doctrine; discrimination.
3. hatred or intolerance of another race or other races.

I place this photochop in the same category as political jabs of McCain and “Depends” (which I thought were funny). It’s a humorous association between witch doctors and government run health care. Is this tacky? Sure, just like the McCain jokes were. Where does the racism come in?
