Two separate, rival groups supported Proposition 200. The first group was the proposition's sponsor, the Protect Arizona Now (PAN) committee, led by Kathy McKee and supported at the national level by the Carrying Capacity Network (CCN) and Population-Environment Balance (PEB). The second group was the Yes on 200 committee, led by Rusty Childress, a Phoenix-area car dealer, and supported at the national level by the Federation for American Immigration Reform (FAIR). There was a split within PAN, which McKee described as an "attempted hijacking of a local effort by greedy, out-of-state interests"; this split highlighted an ongoing feud within the immigration reduction movement between FAIR and the other two groups dating back to at least 2003, with CCN and PEB issuing frequent statements accusing FAIR (as well as NumbersUSA) of being "reform lite" and "undermining real immigration reform."
