From what I understand Napa seems to be very big on the Madeira archipelago and their song is the one with the most listens of the lineup, a little more than 21k, for comparison Josh has 15k, Henka 13k and Fernando Daniel 12k.
I do believe that Josh is the one that will gather the most consensus from the judges and televote, but I don't think that it will be that hard for Henka to get votes from the non-bubble, there's a big incognito regarding the staging, but people voted for Dapuksportif in 2023, they even got the 8 points, third place, from the televote in the final, and I know, they where rock and Henka is nu metal(I think), but there are people outside of the bubble that are into this kind of music and hopefully they will support her.
At the time, there was talk of a strong union around Peniche and the surrounding areas to support the song. Still, 9.17% is something, considering Mimicat won with 19.33%.
Since we don’t know the exact number of votes, it’s hard to calculate or draw significant conclusions. But the truth is that the televote has been very balanced since RTP started showing the percentages. For example, João Borsch won with only 17% (against Iolanda’s 16.29%).
I’ve seen a metal group on Facebook discussing Henka, but many comments also mentioned that "it wasn’t worth the effort to call."
More than in other countries (although the Portuguese fans' favorites almost always win), things here tend to be very close.
I can easily see the jury supporting songs like Josh or Diana, while the televote is likely to favor Henka and Fernando Daniel, who will probably secure the 12 points.
How the jury will evaluate Henka song is a big question mark (but I wouldn’t say it will get significant support).
If Josh manages to capture a good percentage of the Portuguese fans' votes (who seem to be divided between him and Henka), he could certainly also attract a share of the general viewers’ votes—unless his performance is overly bold, which his song doesn’t require anyway. In this case, I think he could be the winner. Personally, at the moment, I think he’s the favorite, potentially scoring 12 + 8 points.
Napa could complicate things if he manages to secure a high percentage of the televote (which is highly likely).
