Open primary goes back to court
Paul Johnson, Chairman of the Open Elections/Open Government initiative, talks about legal efforts to get the proposition on November's ballot.
Johnson says the Maricopa County Elections Department was wrong when it decided initiative supporters didn't turn in enough valid petition signatures.

Opponents, meanwhile, say signatures were invalid and some of them were collected by convicted felons, which would not be allowed.
