Girls State... help?

I want to run for governor at Girls State this year but I am afraid of having to write and prepare all of my materials there, without being able to use any internet sources. I am also afraid that some of my ideas: i.e. health and nutrition being important, won’t be a good (popular) foundation to win. I’ve heard governors usually stick to a platform involving civil rights issues, would it be bad for me to instead choose health as the main priority? How would i be able to prove my points without being able to source documents and studies? Please help!

I know in my state, one girl that got elected senator focused on tax bracket changes.
