CNN's Alexandra Jaffe reports that a new poll shows Americans oppose President Obama's handling of the ISIS threat by a 17-point margin:

Americans are increasingly unhappy with President Barack Obama's handling of ISIS, and a growing share of the nation believes that fight is going badly, according to a new CNN/ORC survey released Monday.

The CNN/ORC poll found 57% of Americans disapprove of how Obama is handling the threat posed by ISIS, a significant decline in support for the President over the past few months. In late September, that number was 49%.

The poll was conducted February 12 to 15, almost entirely before news circulated that ISIS had beheaded 21 Coptic Christians in Libya.
