First off, I got an A+ on each of my last two persuasive essays, so I hope I know what I'm doing. 
You should have actually read the whole address before writing the essay (I gather that you didn't). There are many points beyond the call for nonpartisanship. Was American neutrality, which was generally pursued until WWI, a good thing? What about Wilson's abandonment of it? Washington also mentioned America's homogeneity in his call for nonpartisanship. Is that relevant today? Explore at least two or three points.
I think you should rewrite it, and that it could use a little more time. Even if it's due tomorrow, it's only 9 in Idaho. 45 minutes will do wonders.
When I was thirteen, I tended to do it at 6am the day it was due
