One of the points of contention on the left was that the surge had to produce political progress for it to be successful and here is Pelosi admitting that they achieved it. It looks like the left just lost a talking point:

The prime minister returned to Baghdad from Mosul — where he has been overseeing the crackdown — to meet with House Speaker Nancy Pelosi, who made a surprise visit to Iraq on Saturday.

Pelosi, a top Democratic critic of the U.S.-led war in Iraq, expressed confidence that expected provincial elections will promote national reconciliation.
She welcomed Iraq’s progress in passing a budget as well as oil legislation, and a bill paving the way for the provincial elections in the fall that are expected to more equitably redistribute power among local officials.
“We’re assured the elections will happen here, they will be transparent, they will be inclusive and they will take Iraq closer to the reconciliation we all want it to have,” said Pelosi. She also met with Iraq’s parliament speaker Mahmoud al-Mashhadani, U.S. Ambassador Ryan Crocker and Gen. David Petraeus, the top American commander in Iraq.
Pelosi, who also traveled to Iraq in January 2007 shortly after the Democrats assumed congressional control, has been a sharp critic of the Bush administration’s conduct of the war and has pressed for the withdrawal of U.S. troops from the country this year.
