Create a winning mobile app design

Vote4US is a mobile app that enables the over 132 million voters to compare and discover candidates with similar views through the use of entertaining quizzes, activities/games, and access to an aggregation of unbiased information on each candidate.

http://www.vote4.us (but use for materials and logo, not design)

Font: Trajan Pro (but additional use of san-serif font too is OK)
I already have a logo designed, so the app should take some design queues from that. http://www.vote4.us/
Don't look at any other part of the site except logo (web site re-design will be another project ;-)

I have app blueprinted on my site: http://www.vote4.us/ in the design section.  The blueprints are for iPhone, but I need to see this for iPad.  I think a lot can be done with the extra space.  Keep in mind that the iPhone app will need to have a similar graphic feel to the iPad design created here.  Also, it is likely that I will be negotiating with the winner to create the rest of the needed screens for both the iPad and the iPhone version of this app.

Make sure the design says party agnostic. (of all parties, not just the prominent two)
