While I understand your eagerness to defend your choice, I think you should still pay attention to what other (probably more experienced) members are saying. Oprabama as a combination? Then why not drop another name into it and make it a threesome... That ought to be even more valuable right? Hell, why not just make a combination of all the candidates names... minus one letter of course. Google results you were quoting are also a joke... it returns 900 results, for gods sake.
Seriously though, I'm not trying to mock you, I'm writing this with best intentions and am only trying to make you understand our point. But feel free to put up some interesting content that somehow correlates to both individuals mentioned, market it a bit and you might even get something for it in return. For the name itself however, I really don't see any value...
Don't feel bad about it though, I'm pretty sure most of use have registered just as bad names in the past and still might do so every once in a while, even after being in this business for years... Sometimes gut feelings can be misleading, while rash reactions following them can produce some very strange, odd and even stupid names we end up being ashamed of
