I wouldn't go this far since every poll I have seen that included the robins had Damian being last and even official one from DC last year.I've said this before, but at this point, I think Damian has more fans that Tim and Jason, but at the same time, he has more people who dislike him than Tim and Jason.
Damian is getting more exposure beccause he is the current Robin. After he move on from the mantle and has his own thing, we will see how truly popular and successful he is.
