Thanks to American Conservative Union chairman Al Cardenas, we now know why New Jersey Governor Chris Christie wasn’t invited to CPAC this year: he’s too sympathetic to disaster victims and poor people who need medical help: The Real Reason Why Chris Christie Wasn’t Invited to CPAC.

In other words, he’s not quite heartless enough.

Cardenas, whose group organizes the conference, wrote in an e-mail to National Journal that while CPAC was “proud” to invite Christie last year based on his record of balancing the budget and taking on teachers unions, Christie’s record over the past year is far less conservative.

“CPAC is like the all-star game for professional athletes; you get invited when you have had an outstanding year,” Cardenas said. “Hopefully he will have another all-star year in the future, at which time we will be happy to extend an invitation. This is a conservative conference, not a Republican Party event.”

Cardenas cited Christie’s decision to expand Medicaid under President Obama’s health care law and his support of a $60 billion aid package for Hurricane Sandy victims, which he argued was filled with wasteful spending.

“You get invited when you have had an outstanding year.” That must be why Mitt Romney was invited to speak.
