Is this in the rulebook? Is there, um, a rulebook? From Fox News:

Anti-American cleric Muqtada al-Sadr is calling on his supporters and other Iraqis to vote in a referendum this weekend to decide which political leader he should support for prime minister.

Kind of like "Iranian Idol."

Al-Sadr's hardline, religious Shiite party, which won 39 of the 325 parliamentary seats in the March 7 election, has emerged as a key powerbroker whose support will prove crucial in determining which of the two leading blocs will form the next government.

A spokesman for al-Sadr, Salah al-Obaidi, said Wednesday the referendum results would be binding on the party.

Such democractic democrats.

The voting would be Friday and Saturday at al-Sadr offices, mosques and other sites across the country.

Al-Sadr first called for the referendum Tuesday on his Web site.
