Prior to Yar'Adua being chosen as the PDP candidate, I read an article which pointed out that OBJ actually wants Goodluck Jonathan to be the president, but is only using Yar'Adua as cover-up, knowing he will not live to finish his term in office. At first, I took it with a pinch of salt, but it might be true after all.
