President Obama is crossing the sea (Gulf of Mexico?) From the trail he's left behind, we are meant to deduce that he has been walking on water. If you say that someone walks on water, you mean that they can perform miracles, just like Jesus did. In fact, in the early part of his presidency, many people thought that Obama would achieve great things. After all, he won the Nobel Peace Prize and got his health care bill passed. However, the BP oil spill has caused him to slip up, literally in the cartoon, and figuratively in real life, where his response to the crisis has been severely criticized in some quarters.
