Things I should've explained more clearly in the update but was too damn tired to write:
The lack of religion means your support hasn't spread as fast as it should have, but on the other hand it means that you are not a high priority for the Federation at the moment - if they try anything, your information network will find out before their agents act. That will change when they bring in more competent personnel from off-world if you should grow more successful. Furthermore, even as a secular organization the focus has been on you, personally, due to your public leadership of the group. What this means is that rain or shine, whatever you do reflects on the organization as a whole, and vice versa. Your name and status is public. Expect everything you do to come under scrutiny.
The aid you provide is less towards doling out food and money, but more towards knowledge. Think of an order of monks instructing the illiterate on how to read and write. Well, the refugees are literate, but you do make an effort to teach them other more useful technical skills. Plumbing. Electrical works. Basic engineering. Anatomy & medicine. How to defend themselves. Of course you do give out whatever excess food that you cannot sell to the poorest of the quarter, but your aid is mainly in the form of knowledge.
Furthermore, you've already seen the first attempt to get your organization on their side. There will be more to come. When you increase your influence further, the cartel bosses will no longer be able to ignore you and will contact you directly instead of doing their dirty work through the small gangs. The Governor himself, once he takes notice of what's happening under his nose, will not stay silent either, and will surely call for a meeting to gauge which side of the fence you're on.
Then, there's the Federation and the Star League, which cannot be considered synonymous. You might do well to play one off against the other, like Qin does, when the time comes.
And finally, the ex-Emperor still commands considerable prestige and sway over the Ankidans despite having retired...
You don't need to become president if you don't want to. Qin's pet politician. The Governor. Perhaps one of the major crime bosses. Maybe even Kyrie's father. You can raise either of them to the presidency, which is possible because in their haste to escape the dying Earth Julia made a mistake in amending the laws of the Federation to stay in power. You'll be exploiting that loophole. You're not throwing in your lot with Qin just yet because it's still two months to go till the election comes and you are building up your power as the kingmaker. Sure, she might be the one with most faith in you, but it doesn't hurt to wait for the other choices to pop up (which will happen as soon as the next update, with the available options actually depending on what you pick here).
Helping people was always just the means to an end for this path we've chosen. Not the goal itself.
