Hillary Clinton once again attacked Barack Obama on the issue of experience Tuesday, this time questioning the Illinois senator's ability to effectively smile, make appropriate eye contact, and offer sufficiently delicious finger foods when welcoming visiting world leaders. 'My opponent has never greeted foreign dignitaries such as the Japanese Minister of Forestry and Fisheries, as I had the opportunity to do when I was first lady,' Clinton said, adding that she has an extensive background in both double-clasped hand shakes and idle small talk with political luminaries from several nations. 'Do the American people really want a president who doesn't know when it's appropriate to gesture toward a chair, indicating where a head of state should be seated?' At a previous speech in Indianapolis, Clinton had challenged Obama's ability to create a health-care reform initiative that would ultimately fail and hand Congress over to the Republicans in an electoral landslide, as she did in 1993.
