I’ve seen it spelled both ways, so I went to Google to find the answers.

Personalized Results 120 of about 102,000 for Obamessiah. (0.08 seconds)

Personalized Results 120 of about 23,500 for Obamamessiah. (0.15 seconds)

I suppose the 102,000 result count of Obamessiah makes the most sense, when the word is pronounced aloud. I doubt we will ever know who coined either word.

Obamamessiah search results even starts off with a blogspot blog (“Is Barack Obama the Messiah?”) entitled with the word.

Obamessiah search results begin with a Michelle Malkin article. That probably carries more weight. Should I rename my series?
