How Americans are feeling about the country's 250th anniversary, according to new polls

A new survey shows about 40% of U.S. adults feel 'proud' and 30% feel 'excited' about the U.S. 250th anniversary, with Republicans and older adults expressing stronger positive sentiments. However, many Americans, particularly Democrats and younger people, feel indifferent or conflicted, and some believe the nation’s founders would be disappointed with current conditions.
