In 2005, Kenya held a constitutional referendum which KANU opposed. Some members of the ruling NARC coalition government, mainly former KANU Ministers who had joined the opposition coalition in 2002 under the LDP banner and who were disgruntled as the President Kibaki had not honoured a pre-election MoU on power-sharing and creation of a Prime Minister post, joined KANU to oppose the proposed constitution. The symbol of the "No" vote was an Orange. As such, this new grouping named their movement the Orange Democratic Movement (ODM). Ruto was a leading light in this movement and part of its top brass dubbed, the Pentagon. He solidified his voter base in the Rift Valley Province. ODM was victorious in the election.
