Nearly three-quarters of Americans say the situation at the border with Mexico is a crisis (74%), up from less than half who felt that way in January (45%), according to a new CNN poll conducted by SSRS.

Here are the other key takeaways from the poll:

The steep increase comes most sharply among Democrats, though there are increases across party lines:

Back in January, just 23% of Democrats called it a crisis as President Trump took that line in an effort to build support for funding to build a wall along the border. Now, 70% see it as a crisis.

Among independents, the share who see a crisis has climbed from 47% to 72%

Among Republicans, it’s up 11 points to 82%.

Trump's approval rating stays the same:

The same poll finds little movement in Trump’s approval rating over that time for handling immigration (42% approve now, 41% did in January). Trump’s overall approval numbers hold steady in the new poll at 43% approving and 52% disapproving.

There is disagreement across party lines about the cause of the crisis at the border:

A majority of Democrats consider it a crisis because of the treatment migrants are receiving as they attempt to cross the border (54%).

While most Republicans say they think it’s a crisis because of the number of migrants attempting to enter the country (63%).

Among independents, slightly more say it’s a crisis due to the number of migrants attempting to cross (35%) than because of the treatment migrants are receiving (28%).

About six in 10 Americans (62%) say they disapprove of the treatment migrants are receiving at the border, but there’s a steep partisan divide here as well:
