A new TV ad that urges Congress to oppose U.S. military strikes against Syria underscores the difficulty President Barack Obama is having in getting war-weary liberals to support him.
The 30-second ad by the activist group MoveOn.org says the U.S. didn't set out to spend eight years at war in Iraq and a decade in Afghanistan, and predicts the same thing will happen if Congress approves Obama's desired military action in Syria.
Obama says the government of Syrian President Bashar Assad should be punished for carrying out a deadly chemical weapons attack last month outside the capital of Damascus.
The ad, titled "Not Again," concludes by telling Congress, "Don't lead us down this road again." Viewers are given a telephone number and urged to call Congress to voice opposition.
MoveOn says the ad will air this week on MSNBC, with a special focus around Obama's planned address to the nation Tuesday night.
