There are some striking divides in a new CNN poll, but they aren’t necessarily the partisan kind Americans have come to expect: The divides are more gray than red versus blue.

The first has to do with the American Dream, which a growing number of Americans feel is out of reach. Most, 54%, still agreed with the idea that “people who want to get ahead can make it if they’re willing to work hard,” in the new poll, conducted by SSRS.

What’s noteworthy is that when asked the same question back in 2016, more than two-thirds of respondents, 67%, agreed with that optimistic idea.

Looking at the new poll’s results by age, younger Americans are less bullish that they can “make it.”

About half, 51%, of those under 45, felt that “Hard work and determination are no guarantee of success for most people,” compared with 41% of those 45 and older.

There’s likely some partisanship behind those numbers, since younger Americans tend to be more liberal, despite the inroads that President Donald Trump and Republicans have made with young people.

But the age divide exists, to a more modest extent, even within the Democratic Party. More than two-thirds of Democrats and Democratic-leaning independents under 45 say that hard work and determination are no guarantee of success. A smaller portion, 62% of older Democrats and Democratic-leaning independents feel that way.
