Who got the biggest gains in Ariz. voter registration?

Would-be voters have burned up the registration forms since the Aug. 30 primary election. The Arizona Secretary of State’s Office reported a 5.5 percent increase in the voter rolls since the Aug. 30 primary election, with 187,855 people signing up to vote.

For voters — whether new or tenured — who have an early ballot, elections officials are urging them to mail it back to their county recorder by Tuesday. After that, voters should walk their ballot into any polling place on Nov. 8.

So what allegiance are these new registrants showing? Republicans have hung on to their status as the state’s largest party, edging out independents by about 20,000 voters.

The registration flurry showed Democrats increased their rolls by a greater percentage than the GOP. But the Greens made the biggest percentage gain, swelling their comparatively tiny rolls by 25 percent. Here’s how the numbers break down by party:

The overall increase is the largest since 2008, when Barack Obama and John McCain were running for president.
