Councilmember James Rodriguez posted something on his personal facebook not too long ago
Latest poll in SD 6 race: Alvarado 42% Garcia 34%. Way 2 go Carol
So, in addition to being able to put Rodriguez firmly in the Alvarado column, it raises the suspicion that there is actually a poll out there. Comments on his status asking for a link have not been responded to as of now. I will probably just update this page when I have more info.
