It is impossible for an individual - even a deputy president to beat a determined controller of State in parliament.
Matiba deployed all his resources to bankroll Orengo's no confidence vote. The first attempt was frustrated by the speaker. The second went through to debate and vote.
A day before Matiba had the numbers to send Moi home. But by the time the debate started and millions of shillings and shocking threats - even one kidnapping - Moi had taken the initiative.
In the end they discovered they did not need to play hardball. No MP wanted a new election and they wanted was cash.
Thus on his second attempt, Moi did not deploy his dogs. He simply dished out cash. He then developed the bribe window where loyal MPs (including opposition moles) would receive handouts from specific people. Later the window at Internal security was introduced. Kibaki inherited and he thought it was a good idea.
Pundit needs to review others who at some point controlled a large number of MPs. In Kenya that leads nowhere. It is like the roosters comb: looks red and dangerous but quite harmless and delicious for the fox.
