Politics, politics and more politics. So much politics, that we've decided to mega-size our mega-sized Political Junkie this week. Ken Rudin will be with us for the full first hour, which will be divided into three segments. In the first part of the hour, we'll talk more about the speech made yesterday by Barack Obama, explain a just released 11,000 page document outlining Hillary Clinton's time and involvement as First Lady, and discuss John McCain's recent gaffe during a Middle East tour. Our second Political Junkie segment will focus on the impact Obama's speech made on white voters, and why white voters in mostly urbanized areas are not as enthusiastic about voting for Obama. And in the final segment, we will talk with Iraq war veterans who are running for Congress and find out whether their war experience plays into their campaigning.

In our second hour of Talk of the Nation, we will commemorate the fifth year anniversary of the Iraq War. Eric Owles, chief multi-media producer for NYTimes.com, will talk about his travels around Baghdad and the experiences told to him by Iraqis about life in the region since the start of the war. Following that conversation, we'll focus on the medical care system for those who have been wounded in the war, and provide and update on the current conditions at Walter Reed Army Medical Center.
