The Times report indicates that leading Sunnis will join the political process after the election at the end of the month. Again, it doesn't mean the violence will vanish overnight, but it's definitely a sign that some people who are opposed to this process now see it as unstoppable.
Those saying they want to become involved in the process are not leaders of the Sunni-dominated insurgency, and there is no indication that the violence will abate after the vote. But some of these Sunni leaders, who include powerful clerics, have considerable influence with the guerrillas and could act as a bridge between the new government - expected to be dominated by the majority Shiites - and the insurgency.
