60 percent say Obama does not have plan for defeating ISIL, 23 percent think he does

CBS News:

Just over a week after the terrorist attacks in Paris, only 23 percent of Americans think President Barack Obama has a clear plan for dealing with the militant group ISIS, the lowest number yet recorded in the CBS News Poll. Sixty-six percent do not think he has a clear plan - a new high.

Large majorities of Republicans and independents say the President doesn't have a clear plan, and almost half of Democrats (40 percent) agree. More Democrats (45 percent) say he doesn't have a plan than say he does.

In considering military options, 50 percent of Americans now favor sending in U.S. ground troops to fight ISIS militants in Iraq and Syria, up four points from August. Support for sending ground troops rose to 57 percent in February in the immediate aftermath of the death of aid worker Kayla Mueller, but then dropped below 50 percent until now.

Two-thirds of Republicans favor using U.S. ground troops to fight ISIS, while about half of Democrats oppose that. Still, support for using ground troops has inched up among Americans across the political spectrum.

Most Americans (63 percent) think ground troops will be necessary to remove the threat from ISIS militants; just one in five thinks the threat from ISIS can be removed using airstrikes alone. Majorities of Republicans (73 percent), Democrats (59 percent), and independents (60 percent) think ground troops will be necessary. Views have changed little over the past year.

The poll also shows that a majority oppose bringing in Syrian refugees to the US.

This looks like a vote of no confidence in the President's strategy.  His restrictions on air attacks makes the current plan less than feasible even as a war of attrition.  It si pretty clear that to deny ISIL control of the real estate they now occupy it will take ground troops.  Air power by its very nature is transitory in effect denying access for the brief period of time it takes a bomb to explode.
