Yoon Decision Timeline Info
Folks in the Sam Yoon circle say that the councilor has scheduled the weekend of February 7-8 to sit down with his family and discuss whether to commit to a mayoral run. Thus, the earliest he will announce his intentions is two weeks from today, at least as plans currently stand.
The guessing is that the answer will be yes, and that he will likely announce within a week after that "family decision" chat.
