We know from bare statistics and clear proclamations that John Lennon (and the Beatles) were bigger than Jesus. Now, we're starting to get evidence that Barack Obama is bigger than Lennon. We can tell this because Julia Sweeney replaced her "Imagine No Religion" bumper sticker with a Barack Obama sticker, as she noted on her blog on April 15th.
Clearly by the transitive property if John Lennon > Jesus and Barack Obama > John Lennon therefore Barack Obama > Jesus.
In other news, Julia Sweeney has a blog... and it's remarkably good.
