Summary of Pew Research Center Survey on U.S. Campaign Against ISIS (October 2014)

Core Content

The Pew Research Center conducted a national survey from October 15-20, 2014, involving 2,003 adults, to assess public opinion on the U.S. military campaign against Islamic militants in Iraq and Syria, particularly ISIS. The survey highlights both support for the campaign and significant doubts about its effectiveness and clarity of objectives.

Main Findings

• Overall Support:

  • 57% of Americans approve of the U.S. military campaign against Islamic militants.
  • 33% disapprove.
  • Support is highest among Republicans (68%), followed by independents (55%) and Democrats (54%).

• Perception of Campaign Effectiveness:

  • 64% of Republicans, 61% of independents, and 52% of Democrats believe the military campaign is not going well.
  • Only 30% of the public thinks the U.S. and its allies have a "clear goal" in the military action.

• Concerns About U.S. Involvement:

  • 47% of Americans are more concerned that the U.S. will go too far in the conflict.
  • 43% are more concerned that the U.S. is not going far enough.
  • This concern about over-involvement has increased from 41% in mid-September.

• Opposition to Ground Troops:

  • 55% of the public opposes the deployment of U.S. ground troops to fight ISIS.
  • 39% support it.
  • Opposition is widespread across demographic groups, including whites (53%), blacks (62%), and Hispanics (55%).

• Party Line Differences:

  • Republicans are more supportive of ground troops (57% favor) compared to Democrats (66% oppose) and independents (56% oppose).
  • Democrats are more concerned about the U.S. going too far in the conflict compared to Republicans and independents.

• Public Opinion on Allies' Contributions:

  • Only 17% believe that U.S. allies are doing enough to support the military effort.
  • 73% think allies are not doing enough.
  • This sentiment is consistent across most demographic groups, including age, education, and race.

Key Information

• Survey Methodology:

  • Conducted via telephone interviews.
  • Combined landline and cell phone samples.
  • Weighted to match demographic parameters from the 2012 Census Bureau's American Community Survey.

• Sampling Error:

  • The survey has a 95% confidence level.
  • Total sample margin of error: ±2.5 percentage points.
  • Party-specific margins of error: ±4.9% for Republicans, ±4.4% for Democrats, and ±4.2% for independents.

• Trends and Comparisons:

  • Public approval of the military campaign has remained relatively stable, with a slight increase from mid-September.
  • Concerns about over-involvement have risen slightly.
  • There is little change in public opinion on the use of ground troops compared to previous months.

Additional Notes

• The survey includes data on the Tea Party movement, showing that opinions among Republicans have remained largely unchanged.
• The report also notes that survey results can be influenced by question wording and practical challenges, which may introduce some bias.

Conclusion

The survey indicates that while there is bipartisan support for the U.S. military campaign against ISIS, there are significant concerns about the lack of clear objectives and the effectiveness of the campaign. The majority of the public opposes the use of ground troops, and there is skepticism regarding the contributions of U.S. allies.
