Guys, do you really imagine snubbing him will go over well?
First of all, it goes against what our system is supposed to stand for. We elect the best, and in this case, he is clearly the best. If anyone can handle a war, or better yet, stop one, it would be this guy. This guy is better than pretty much anyone else that can be elected, and yet people don't want him because they dislike his policy on one issue.
Second, if we snub him, we now have an entire province that starts to dislike the system and becomes radicalized. It won't be just one or two generations before that dies off, it will be an ongoing problem.
Third, not electing him sets bad precedents. First, all of our other heroes became king, but our martial didn't. What happens when we don't get the loyal and honorable warrior next time? He's going to look at his predecessor and realize that it is quite possible he will never become king because a bunch of old men disagrees with him. Worse, narratively, the reason he is not being elected is favoritism. The chiefs are so sure that they are right that they won't even entertain the idea that this guy could be right about something. This is not something I want our people doing, I want them to elect someone who is competent even if they personally dislike it.
