President Barack Obama yesterday speaking to the troops in Jacksonville:

I won't risk your lives unless it is absolutely necessary.  (Applause.)  And if it is necessary, we will back you up to the hilt.  Because you deserve the strategy, the clear mission, and the defined goals as well as the equipment and support that you need to get the job done.  We are not going to have a situation in which you are not fully supported back here at home.  That is a promise that I will always make to you.  (Applause.)

Sens. Hillary Rodham Clinton (N.Y.) and  Barack Obama (Ill.) announced yesterday that they will support a symbolic vote to cut off funding for combat troops in Iraq within a year, an important shift for both Democratic presidential candidates as the war debate on Capitol Hill intensifies. [snip]

Obama said he will support both Democratic measures "because I want to send a strong statement to the Iraqi government, the president and my Republican colleagues that it's long past time to change course."
