Input: Younger, active-duty military less likely to have an opinion on Obama either way 
  
 PRINCETON, NJ -- U.S. military veterans and those currently on active military duty are less likely to approve of President Obama's job performance than are Americans of comparable ages who are not in the military. 
  
 These results are based on an analysis of more than 238,000 interviews conducted as part of Gallup Daily tracking from January 2010 through April 2011. Respondents were classified as veterans/active-duty military based on responses to a series of questions probing whether any member of the household had served in the U.S. military, and whether the respondent himself or herself had served and, if so, whether the respondent was currently on active duty. Americans currently serving in the military overseas or on ships at sea would not be included in this national cell and landline telephone sample. 
  
 Thirty-seven percent of all active-duty military personnel and veterans surveyed approved of the job Obama is doing during the January 2010 to April 2011 time frame. That compares with 48% of nonveterans interviewed during the same period. 
  
 Obama's approval rating varies by age, with younger Americans in general most likely to approve and older Americans least likely. The gap in approval between veterans/active duty military and nonveterans persists across the age spectrum, from 18- to 29-year-olds to those 80 and older. 
  
 Differences Across Gender Groups 
  
 Veterans and active-duty military, particularly those 40 and older, are predominantly men, and men are less likely to approve of the job Obama is doing than are women. However, the gap in Obama job approval between veterans/active-duty military and nonveterans persists among men in each age group. 
  
 Women who are serving or have served in the military are on a relative basis more positive about Obama than is the case for men who are members of the military or veterans. Female veterans or those in the military between the ages of 30 and 49, for example, are actually slightly more likely to approve of Obama than are nonveteran women in this age group. 
  
 Active-Duty Military Less Likely to Express an Opinion on Obama 
  
 Although active-duty military personnel are less likely to approve of the job Obama is doing than are national adults overall, this group's disapproval is only marginally higher than that of national adults. This is because active-duty military -- particularly those under 40 -- are significantly more likely to say they have no opinion about Obama's job performance than is the case for all adults in the same age group. 
  
 There are several possible explanations for this finding. Those on active duty may in general be less involved in politics and current affairs and thus less likely to hold an opinion on Obama or other political matters. Or, it could be that members of the active-duty military are adhering to a general nonpartisan norm within the military culture, and are therefore less willing to express an opinion to a survey interviewer, regardless of what they may actually believe. 
  
 Military Service Rare Among the Young, Highly Prevalent Among Seniors 
  
 The basic pattern of military service among Americans is remarkably -- albeit not surprisingly -- differentiated by age and gender. Across all age groups, most active-duty military personnel and veterans are men. For American men under age 60, the percentage who have served or currently serve in the military ranges from 8% in the youngest age group to 21% of those aged 50 to 59. The percentage of military veterans is much greater among those 60 and older, reaching a peak of 75% among men aged 80 to 99. 
  
 Bottom Line 
  
 Americans who currently serve or previously served in the U.S. military are less likely to approve of the job President Obama is doing than are those who have not served in the military, by about 10 percentage points. This approval gap occurs across age groups. 
  
 For younger, post-draft-era veterans, individuals with certain regional, demographic, or psychographic backgrounds may be more likely to be Republican and more likely to join the military. For older veterans, their service in the military may have led them to a more Republican viewpoint on politics, either during their service or in later years. ||||| Laura Youngblood prays over the grave of her husband Travis L.

 Americans from Washington to California were marking Memorial Day with parades, barbecues and somber moments of reflection in an annual holiday infused with fresh meaning by the approaching 10th anniversary of the Sept. 11 terrorist attacks. 
  
 The anniversary was incorporated into the National Memorial Day Parade in Washington, where special tributes were held for the first responders to the attacks and to the relatives of the thousands killed. Actor Gary Sinise, a veterans advocate who played Lt. Dan in the film "Forrest Gump," and Medal of Honor recipients from the Korean and Vietnam wars were among the guests. 
  
 The public holiday recognizes America's war dead, though the 10th anniversary of the terror attacks adds even more meaning for those who were the first to help when the attacks happened. The holiday also comes less than a month after U.S. Navy SEALs shot and killed Osama bin Laden in Pakistan. 
  
 Sgt. James Patrick McMichael of the Arlington County, Va., sheriff's office was part of a team of first responders to the Pentagon. He said he was diagnosed with post-traumatic stress disorder about two years after the attacks and that, even though the looming anniversary was dredging up painful memories, it was still critical that the public remember what occurred. 
  
 A commercial jet crashed into the Pentagon on Sept. 11, killing 184 people at the sprawling Defense Department headquarters. 
  
 "Reliving the event is not something that I look forward to, but I don't think it should be something that's not brought up to the public," said McMichael, who attended the parade in Washington. "I don't think people should forget about what occurred." 
  
 Hamilton Peterson, who lost his father and stepmother aboard United Airlines 93, which crashed into a field in Shanksville, Pa., said the looming anniversary should inspire Americans to be vigilant against future terrorist attacks. 
  
 "Obviously, bin Laden's death is a highlight of the 10th anniversary. However, we recognize that future attacks are imminent and that, absent using 9/11 as a model for how to respond, all Americans need to get involved. It can't just be the military," the 51-year-old said. 
  
 President Barack Obama was participating in a wreath-laying ceremony at the Tomb of the Unknowns at Arlington National Cemetery. 
  
 "Our nation owes a debt to its fallen heroes that we can never fully repay, but we can honor their sacrifice," Obama said at a Memorial Day service at the cemetery. "And we must." 
  
 Meanwhile, U.S. troops fighting in Afghanistan paused to remember the fallen in Memorial Day services, with some praying and holding flag-raising ceremonies to recognize the more than 1,400 who have been killed in combat there since the war began a decade ago. 
  
 President Barack Obama plans to draw down U.S. troops across the border in Afghanistan beginning in July, while NATO has committed to handing over control of security in the country to Afghans by 2014. For now, though, the war continues. 
  
 "We reflect on those who have gone before us. We reflect on their service and their sacrifice on behalf of our great nation," said Brig. Gen. Lewis A. Craparotta, who commands a Marine division in Afghanistan's southern Helmand province. "We should also remember those serving today who embody that same commitment of service and sacrifice. They are committed to something greater than themselves and they muster the physical and moral courage to accomplish extraordinary feats in battle."

Output:
President Obama made a visit to Arlington National Cemetery today, where he placed a wreath at the Tomb of the Unknowns, reports the AP. "Our nation owes a debt to its fallen heroes that we can never fully repay, but we can honor their sacrifice," he said at a Memorial Day service there. "And we must." But in other troop-centric Memorial Day news, Gallup reports that veterans and active-duty military personnel are less likely to approve of the job Obama is doing than similar age, non-military Americans. Using data from 238,000 interviews conducted between January 2010 and April 2011, Gallup found that 37% of veterans and those on active duty gave Obama's performance a thumbs up, compared to 48% of nonmilitary responders. But it turns out active-duty personnel aren't much more likely to disapprove. Instead, they're more likely to say they have no opinion, by as many as 11 percentage points. Gallup speculates that could be because they are "adhering to a general nonpartisan norm within the military culture, and are therefore less willing to express an opinion."
