Ramadi is part of the Sunni triangle...in Al Anbar province which has elected the Iraqi Islamic Party (the IIP is the Iraqi branch of the Muslim Brotherhood). This (Al Anbar) is reportedly where Zarqawi and his merry men plan to establish their Islamic Caliphate of Iraq. Al Anbar province is that area in western Iraq that abuts Syria, Jordan and Saudi Arabia.
Here is a link to Global Security's comments on the IIP...
And as to the Muslim Brotherhood, here is their motto:
"Allah is our objective. The Prophet is our leader. Qur'an is our law. Jihad is our way. Dying in the way of Allah is our highest hope."
