But first, consider this: How would the storm have been covered if a Republican were president? And how would Katrina have been covered if Obama had been president and Bobby Jinadal had been governor? The media would likely have blamed the Republican, whichever one they could find. From what I know, there is enough suffering that the media could blame anyone they want. They did it in 2005, that's for sure.
Christie, by figuratively and literally wrapping himself around Obama, has insulated himself from most criticism by the media. Whether that was his purpose or not is another question.
Yes, Christie should re-affirm his support of Romney. He has to choose his own future (which he won't have anyway if he loses Republican support) or the good of the country.
Christie is focused on the disaster in New Jersey. He’s doing the best he can to help his people. Critics don’t know what he’s dealing with.
