A super PAC opposing Chris Christie’s (R) presidential bid said Tuesday that it planned to shut down, citing the New Jersey governor’s poor performance in the polls.

The treasurer of the Stop Chris Christie PAC, Thomas Bjorkland, made the announcement in response to a letter from the Federal Election Commission that warned the super PAC must change its name or else clarify the nature of the committee. Bjorkland wrote in a letter to the FEC that “based on recent polling and the miserable showing of the candidate in question,” the committee decided to instead wind down its operations.

“Our committee believes that Mr. Christie has already performed the service of stopping his campaign in spirit, (without our aid) even if not by the letter of the law,” Bjorkland wrote in the letter. “Therefore, we intend to stop (cause to come to an end) the Stop Chris Christie PAC within the next 30 days.”

A CNN/ORC poll released Aug. 19 showed that Christie polled in 11th place in a crowded GOP presidential field.
