Perhaps the luckiest politician in America this week is Gov. Chris Christie (R). The New Jersey Republican inadvertently touched off a ridiculous conversation about the politics of vaccinations on Monday, and was poised to be at the center of an ugly controversy – right up until Sen. Rand Paul (R-Ky.) eclipsed him with even more problematic comments.

As of last night, the Republican senator was still trying to work his way out of the hole he’d dug for himself.

Sen. Rand Paul (R-Ky.) on Wednesday continued to walk back his comments that parents should be allowed to choose whether to vaccinate their children, saying he holds the same position as President Barack Obama on the matter.
