Cardon is running in the primary to the right of Flake, who is one of the most fiscally conservative members of the House but has avoided harsh rhetoric on social issues and immigration.
“Amnesty is an unconditional pardon for a breach of law, and Congressman Flake has never supported amnesty,” said Flake spokesman Andrew Wilder.
Cardon launched his first ad of the campaign last week — a hefty statewide buy totaling about $230,000. But the ad backfired for Cardon when it was revealed that Tucson, the second-largest metropolitan area in Arizona, was misspelled in the ad.
Cardon has also raised eyebrows by bringing former Republican National Committee staffer Allison Myers onto his campaign. Myers was reportedly let go from the RNC in 2010 after she approved almost $2,000 in expenses to a bondage-themed nightclub.
