The N&O is reporting that State Treasurer Richard Moore is beginning to assemble a team to make a run for governor. It is also looking more and more like AG Roy Cooper will be running as well. I do not envision any other Democratic contenders except for possibly Lt. Governor Perdue, although it is three years away. I will be putting up bios of Cooper and Moore soon to start getting the early picking started.
Update: Perdue is apparently running. Thanks to James for noting that in the comments. I apologize for being so ignorant as to that fact. Looks like the field is already taking shape three years out.
