For people who are involved in making this year's elections in Ghana more democratic and credible, I read this journal article and thought it was a good read:
The successful Ghana election of 2008: a convenient myth? by Jockers, Heinz; Kohnert, Dirk; Nugent, Paul. The Journal of Modern African Studies 48. 1 (March 2010) 95-115
I dunno perhaps you will need a university log in since I found this through my university library. It's good to look at objective criticisms, so that we know where the hurdles will be and how we can overcome them.
