WASHINGTON (CNN) Amid the longest government shutdown in US history, a majority say Donald Trump bears more responsibility for it than the Democrats in Congress, and the President's disapproval rating has climbed five points since last month, according to a new CNN Poll conducted by SSRS.

Negotiations between the President and congressional leaders have stalled as neither side seems willing to budge on funding for a wall along the border with Mexico. That proposal remains deeply unpopular with the public, according to the poll. Overall, 56% oppose a wall, 39% favor it. That's almost exactly the same as in December. And less than half view the situation at the border as a crisis (45% say it's a crisis, 52% that it is not).

Among those who do see the situation as a crisis, most feel that a border wall would help improve things. The subset who feels that way, however, amounts to only 31% of US adults.

All of these results are sharply divided along party lines. Nearly 9 in 10 Democrats oppose a wall along the border while 8 in 10 Republicans favor one. Seven in 10 Republicans say the situation at the border is a crisis and two-thirds believe a wall would fix it, while about three-quarters of Democrats say there is no crisis, and just 4% feel that there is one that a wall would help improve.
