Clearly the headline is a little bit misleading or incomplete, when compared to its lead, but this is within purpose.
There are two Islamic organizations mentioned in the headline, which is NU and Muhammadiyah. Now compare it to its lead:
Sixty Islamic mass organizations have pledged their support for Jakarta gubernatorial candidate Agus Harimurti Yudhoyono and his running mate Sylviana Murni.
The article actually tries to focus on the number of Islamic organizations which have stated their support for Agus-Sylvi, but the title only mentions two of the biggest ones. I think it is for advertising purposes, ‘subtle clickbait‘ if you will. The author needs only to mention two of the biggest organizations who support this candidate for Jakarta’s new governor election, which is Muhammadiyah and NU. When the author mentions this, he/she expects that the readers will know the significance of the news, since two of Muslim biggest organizations are supporting a certain candidate.
Despite its clever technique to attract readers, I do not find the news informative nor neutral. Since the most controversial or the main attraction of the news are NU and Muhammadiyah, these two organizations are clearly going to be the mentioned a lot in the article. The information about Muhammadiyah stand in the 2017 Jakarta election is clear. There are officials who are quoted in the article and it even mentions official signing.
Sadly, from NU side, there is no clear information whatsoever. The article claims that NU supports this particular candidate without any clarification or quotation from the organization leaders. They only thing mentioned about NU is this line:
The deputy chairman of NU’s Jakarta chapter, Munahar Muchtar, delivered a prayer at the event. He could not be reached for a comment.
Delivering a prayer and inability to be reached for a comment do not clarify the claim that NU is supporting Agus-Sylvi. This, to me, is a loss for the news article’s credibility.
