LAWRENCE, Mass. (AP) - A majority of Americans see no end in sight in Afghanistan, and nearly six in 10 oppose the nine-year-old war as President Barack Obama sends tens of thousands more troops to the fight, according to a new Associated Press-GfK poll.

With just over 10 weeks before nationwide elections that could define the remainder of Obama's first term, only 38 percent say they support his expanded war effort in Afghanistan - a drop from 46 percent in March. Just 19 percent expect the situation to improve during the next year, while 29 percent think it will get worse. Some 49 percent think it will remain the same.

The numbers could be ominous for the president and his Democratic Party, already feeling the heat for high unemployment, a slow economic recovery and a $1.3 trillion federal deficit. Strong dissent - 58 percent oppose the war - could depress Democratic turnout when the party desperately needs to energize its supporters for midterm congressional elections.

A majority of Americans do welcome Obama's decision to end combat operations in Iraq. Some 68 percent approve, a number unchanged from earlier this year. The last American combat brigade began leaving Iraq on Thursday, ahead of Obama's Aug. 31 deadline for ending the U.S. combat role there.
