Incumbent: Nancy Vaughan
Challengers: Justin Outling, Eric Robert, Mark Timothy Cummings
While enough can be said to not support Vaughan for reelection as mayor, here's also the case against Outling getting a promotion. (alternate thread here).
The political clans are out in full force here. Outling, for instance, is backed by the Marty Kotis and Jim Melvin factions. Not to mention, they all hate Robert since he called them out in the past.
The only good thing about Vaughan reneging on her 2017 campaign pledge not to run again is that she froze out the biggest opponent of any kind of police overhaul on the City Council. Let's face it, if Marikay Abuzuaiter had run for mayor against Outling in an open contest and had there not been any Census delays, many East Greensboro residents would have begrudgingly supported the latter simply to stop the "fund the police" candidate.
As bad as the two members of the City Council are on policing, the outsiders are only slightly better on the issue as these two tweets from a People's Freedom Assembly member attest (i.e. Cummings and Robert are more incrementalistic).
