Some of this material has been covered elsewhere but it merits inclusion here...
...In CD3, attorney Paulina Morris has filed for a run at the R nomination to replace the soon-to-be retired John Shadegg. A name familiar to most AZ political geeks, Lisa Graham Keegan, has signed on as Morris' campaign treasurer. Keegan is a McCain confidant/ally and former State Superintendent of Public Instruction.
...In CD8, R candidate Thomas Carlson has ended his run for the chance to take on Democratic incumbent Gabrielle Giffords. I don't know much about him or his reasons for running, but his reason for dropping out may be related to the fact that he raised a little over $2K for his campaign.
...In CD8, R state senator Jonathan Paton has finally resigned from the Senate to pursue his quest to unseat Giffords. He filed for his run weeks ago, so this wasn't unexpected.
...In CD1, R candidate Thomas Zaleski of Sedona has filed for a run at Democratic incumbent Ann Kirkpatrick.
...In CD5, perennial R candidate Susan Bitter Smith has filed for another run at Democratic incumbent Harry Mitchell. She is a former member of the Scottsdale City Council and a current member of the Board of Directors of the Central Arizona Project. She is also a long-time lobbyist, mostly for the telecom/cable TV industry. Her entry into the race has long been rumored, so this isn't exactly a surprise.
...Also in CD5, R candidate Eric Wnuck has withdrawn from the race for his party's nomination. He cited family/business concerns, but a growing field in the R primary and a shrinking pool of available money may have had an impact on his decision, too. In his latest campaign filing, he listed donations at $52K; his first filing listed contributions of over $160K. That's a significant drop during a period when most campaigns are ramping *up* their fundraising efforts.
In Arizona offices...
...State Rep. David Bradley has filed for a run at Arizona Corporation Commission (filer ID 201000475). AZBlueMeanie at Blog for Arizona has coverage here.
...Doug Ducey, a Scottsdale businessman, has filed to enter the race for the Republican nomination for State Treasurer. Ducey is the former CEO of Cold Stone Creamery, so he has deep pockets, but he isn't exactly as popular as Cold Stone.
...In a sign that the Rs consider Democratic Attorney General Terry Goddard to be a very strong candidate, the Republican Governor's Association has set up a PAC in Arizona so that they can expend monies attempting to influence the governor's race this year (filer ID 201000467).
...In Scottsdale, Republican Linda Milhaven, the former Chair of the Scottsdale Cultural Council, has entered the race for Scottsdale City Council. Her entry into the race has long been rumored and isn't a surprise. There are now eight active committees for runs for the three available seats on the Scottsdale City Council.
