Stab in the dark at most popular:
1. Johnson
2. Denise
3. Chloe
4. Sam
5. Laura
6. Jeff
However, combining the judges scores over the next few weeks will see Denise and Johnson in the skate off (hopefully).
As long as Chloe/Sam/Laura don't come face to face in a skate off - all three will make the final.
However, back to your original question: I do think Chloe's the most popular, yes. She's always third/fourth on the leaderboard and still gets through whilst Sam hasn't really needed the votes up until this stage so it'll be interesting to see what happens in the next couple of weeks.
I definitely think Sam will be in the skate off sometime soon.
Laura and Jeff have both faced the SO twice now so I don't think they're much competition for Sam or Chloe.
