Not sure.
There was a very clear gambit push that apparently nobody followed, and then he voted rej not to have a bad vanity vote.
The Rej vote as a follow-up to get something going made sense.
Can't vanity vote in ToS.
The vote on my slot today was a out of nowhere.
Switching to Gambit made sense.
@Hayumi, why not vote for Gambit right away when the day started?
