Because that's when we'll find out what he really thinks of shit like this:

A comedian impersonating President Obama who was hired to perform here on Saturday at the Republican Leadership Conference delivered racially tinged remarks about Mr. Obama’s heritage and offered a mocking assessment of the Republican presidential candidates. The impersonator, Reggie Brown of Chicago, opened his act by joking about Mr. Obama’s family history, referring to his white mother from Kansas and his black father from Kenya. He said that he was born in Hawaii, adding, “or as the Tea Partiers like to call it, Kenya.” He said that Michelle Obama, the first lady, enjoys celebrating all of February, Black History Month. He said the president celebrates only half the month.

“My mother loved a black man and, no, she was not a Kardashian,” Mr. Brown said later, referring to the family that stars in reality shows. Khloe Kardashian, who is white, is married to Lamar Odom, who is black and plays for the Los Angeles Lakers. The audience, which was nearly entirely white, watched with befuddlement as the impersonator told them to look into the future to see what the Obamas will look like when they are retired. An image of a feuding husband and wife, from the TV show “Sanford and Son,” was flashed on screens in the ballroom.

Obama can't risk coming across as angry—can't be the angry black man—so we're all going to have to wait for his memoirs to find out what he really thought about this.
