Democrats' pride in the U.S. military has fallen dramatically since President Donald Trump's first term, with fewer than half now saying the armed forces are a major source of national pride, according to a new AP-NORC poll released ahead of America's 250th anniversary.

The survey found Democrats are now the only major political group that does not rank the military among their top sources of pride.

Instead, they express roughly the same level of pride in American popular culture as Republicans, even as their views of the military have shifted sharply over the past decade.

According to the poll, Democrats' pride in the armed forces has dropped from 74% in 2017 to 42% today.

Republicans, meanwhile, remain steadfast in their support, with about nine in 10 saying the military makes them "extremely" or "very" proud.

The poll also found Americans overall are less proud of several core institutions than they were in 2017.

It states, "Pride in America's armed forces (78% vs. 59%), history (58% vs. 44%), democracy (42% vs. 28%), and political influence on the world (34% vs. 24%) have all dropped over the past decade."

The report further noted, "Compared to a 2017 AP-NORC Poll during Trump's first term, adults are feeling less pride in several aspects of the country."

One notable exception is American popular culture.

The survey found "Democratic and Republican pride in American popular culture is about the same," making it one of the few issues where the two parties are closely aligned.

Beyond the military, Republicans were also more likely than Democrats to describe America as "great, prosperous, or powerful," say being American is "extremely" important to their identity, and to report flying the American flag daily or on holidays.

The findings come as the United States prepares to celebrate its 250th anniversary on Saturday.

About four in 10 Americans said they feel "proud" about the milestone, but Republicans were far more likely to say they are "excited," while Democrats were more likely to say they feel "conflicted."

The results point to a widening partisan divide over what best symbolizes America.

While Republicans continue to view the military as a cornerstone of the nation's identity, Democrats have increasingly shifted their sense of national pride toward America's cultural influence and entertainment industry.

The poll was conducted April 14-20 and surveyed 2,596 U.S. adults. The margin of error is plus or minus 2.63 percentage points.
