Why is Senator Obama running for President?

A recent report on the Huffington Post pointed out to me, in the candidate’s own words, Senator Obama’s motivation.

According to AP reporter Christopher Wills, the Senator said to his wife:

“Honey, the reason I’m running for president is I can’t be Bruce Springsteen. I can’t be Billy Joel.”

This candid statement made me wonder, what was so wrong about the following ad put out by the Mc Cain campaign?

After all, the candidate himself explains the reason he is running is because he has no other way of becoming a celebrity.
