I suspect there will be malcontents for sure, but abiding by the election results IS the democratic way, as long as the opposition isn't undemocratically constrained.

While there was a number of issues regarding election fraud, they apparently weren't large enough to majorly change the results. The UIA list won a plurality but not an outright majority this time (approx 128 seats in the 275 seat parliment). They need to form a coalition with other parties to form a government. Maram, a coalition of the Accord Front, al-Mutlaq's Dialogue Front (both sunni), and Allawi's Iraqi List (secular shiite) together have approx 80 seats. The Kurds come in with about 58 seats and the rest to smaller parties.

Even if the Kurds join the UIA again in forming a new government there will still be a sizable opposition in the parliment. However the Kurds have not made any decision yet and a lot of talks are going on with them and Maram. UIA will no doubt form the government in one way or another but they won't have the outright majority they had with the interim parliment and the sunnis are guaranteed to not be marginalized as they were after boycotting the first election.

Meanwhile, sunni resistance have essentially declared war on Al Queda.
