In November 2006, voters elected a new Democratic Party majority in both the Senate and the House of Representatives in the 110th Congress, largely with the expectation that they would work to reduce or end American military involvement in Iraq.[3] In December 2006 the Iraq Study Group (ISG), a ten-person bipartisan panel appointed on March 15, 2006 by Congress, released their final report. Also known as the Baker-Hamilton Commission, the ISG was charged with assessing the situation in Iraq and the US-led Iraq War and making policy recommendations. While President George W. Bush praised the ISG's efforts, he rejected many of its recommendations.[4] In March 2007, General David Petraeus, Commanding General of the Multi-National Force in Iraq, claimed that there was "no military solution" in Iraq, and that political negotiations were crucial to forging any lasting peace.[5] By March 2008, the number of U.S. military personnel killed in Iraq had reached 4,000,[6] with many thousands more wounded, and an estimated hundreds of thousands of Iraqi casualties.[7] Also by March 2008, the financial cost of the Iraq War to the United States had surpassed the half trillion dollar mark.[8]
