In the nearly two weeks since I last checked these numbers (back on November 2nd):* Damian Wayne (2006 +) = 30 votes (+ 8)
* Tim Drake (later Red Robin / 1989 +) = 27 votes (+ 5)
* Dick Grayson (Nightwing/Silver Age +) = 26 votes (+ 6)
* Jason Todd (later Red Hood / 1983 +) = 14 votes (+ 2)
NOTE: Golden Age Dick Grayson (pre-CoIE Earth-2 / became adult Robin with JSA) and Stephanie Brown (originally Spoiler, also Batgirl / became Robin in 2004) are still at three votes for each.
Carrie Kelley (Frank Miller's future Robin, 1986 +) has two votes.
One person voted for We Are Robin gang (Duke Thomas, Riko, Dre, Isabella, Daxton, Troy, etc. / 2015-2016).
All other choices don't have any votes yet at present.
