Obama goes door-to-door in Iowa

Barack Obama continued to press a grassroots strategy in his campaign going door-to-door himself in Iowa as part of a nationwide canvassing effort.

The walk emphasized Obama's opposition to the Iraq War.

"The main thing that we want to communicate today is that this war that we've been fighting in Iraq has got to stop, that we can no longer afford $275 million (€198.31 million) a day spent on a civil war between factions in Iraq where there is no military solution to be had, that it's time for us to begin bringing our young men and women home — they have been there long enough," Obama said during a morning talk at a high school in Des Moines.

In the evening, Obama joined Hillary Clinton and John Edwards for a black women's political action group forum.
