My two cents: all we have so far is a list of names of candidates; we have nothing to establish “most well-known” status. A poll might get closer to that, so might some follow-up lists by others who have seen the choices thus far.
For instance I could vote for:
Blair Witch
Blair Brown
Tony Blair
and the one I submitted before, Blair Underwood.
But unless we have some source that ranks these people in some “well-known” ranking, I am not convinced this first phase has done much besides making a list.
Since we haven’t heard back from the OP, I vote that we post a response to any name we feel we have an opinion on, and every poster needs to also provide a new name for people to cogitate.
