:Hello Keli Yen, welcome to the mysteries of Wikipedia. I see that you are full of good intentions, but you have run foul of the Wikipedia rules already, and I'm sorry that your first experience must have been frustrating. As per your edit summary, if you work for Kennedy Graham, there is nothing that you can do about having a conflict of interest - that's simply a given. You should therefore not touch his page. I suggest what you should do instead is the following: 
 :*Post any change that you would like to suggest on the article's talk page in the following format: It currently says: "blah blah blah" Please change this to say the following instead: "xyz xyz xyz" If you've got a source available that confirms the information, please say what that is. Good sources are newspaper articles or books. Questionable sources are things published by the Green Party or Graham himself (same issue - potential conflict of interest). Unsuitable sources are blogs.  
 :*Lots of editors keep an eye on talk pages (Wikipedia is a bit like the GCSB). Somebody will come along and deal with the request. Either, your suggestion gets adopted, or somebody will modify it, or it will get rejected. If it's not adopted as suggested by you, you can expect to read on the talk page why that is. 
 :I hope this will work for you. Any queries, please post them here, or on the talk page.
