To resolve all the speculation. Thats how the team principals have voted
1. Hamilton 35
2. Vettel 22
3. Alonso 12
4. Button, Bottas, Raikkönen 5
7. Ricciardo 4
8. Rosberg, Verstappen 1
Well that's a different picture to the one the OP presented, which missed out the drivers in 4th-7th places plus MV. A rather significant omission...
I'm not one to be critical of polls and at the end of the day at least this top 8 would have the majority of the fans top 8 in it I would have thought - to my mind with the obvious exception of Grosjean for Verstappen - at this early stage.
One observation that I can't ignore is yet again the effect that recent memory/events appears to have on rankings, for these rankings do not match with the Team Principles own rankings over recent seasons.
