Not much to report this time out.
Candidates for most of the "major" offices (statewide, Congressional) have already announced or strongly hinted at their intentions, even if they haven't officially submitted paperwork. New names may still jump into the various frays, but that becomes less likely with each passing day.
For example, state representative Adam Kwasman just announced his candidacy for the Republican nomination for the CD1 Congressional seat currently held by Ann Kirkpatrick.
However, that's not news; it's been widely known for months that he would be pursuing that office.
As for the "minor" offices (legislative, county, municipal), most serious candidates who haven't already filed for a particular office will probably do so by the end of January.
Note: "Major" and "minor" are in quotes because the while the higher-profile statewide and federal offices may get the lions' share of media attention, the lower-level offices have far more direct impact on people's lives. They aren't truly "minor", IMO.
In the little actual news for this post...
...Sandra Kennedy, a former member of the Arizona Corporation Commission, has opened a committee for a run at return to the commission.
...Doug Quelland, a former Republican member of the legislature has opened a committee for a run as an Independent for the LD20 State Senate seat currently held by Republican Kimberly Yee.
...Mario Diaz, a well-known political and public affairs consultant, has opened a committee for a run at an "at-large" seat on the governing board of the Maricopa County Community College District (MCCCD).
...That's it for now, anyway.
