Hello Talista,
I'm not sure that anyone from LucasArts or Lucasfilm will see your post. If you wish to contact LucasArts you can use the postal mailing address on the LucasArts contact page or if you use Twitter you could send a message to @lucasartsgames.
O.k. I'm in Manitoba and it is Election Day today. Well when I got my copy of The Winnipeg Sun this morning there was a reminder ad to go vote from my Progressive Conservative Party with Yoda featured including Yoda stating Today Vote You Will.
No copyright mention of Lucasarts and I am sure without permission of Lucas considering I highly doubt that you would approve the using of Yoda for a political party endorsement.
I have a photo if you would like to contact me via email.
