Arizona releases new voter registration data each calendar quarter. The July 1 figures show that the only qualified party that has gained registration share since the April 1 tally is the Libertarian Party, which went from .656% to .686%. The party now meets the threshold for keeping its place on the ballot, which is two-thirds of 1%. However, the party must remain vigilant, because the tally that counts is the special November 1, 2009 tally, so the party must guard its share between now and then.

Independents rose from 28.50% to 28.93%. Republicans declined from 36.83% to 36.58%. Democrats declined from 33.88% to 33.67%. Greens were virtually unchanged, at .136% in both tallies. Greens are not conducting a registration drive, but instead are doing a petition drive, so as to remain on the ballot for 2010. Thanks to IndependentPoliticalReport for this news.
