Support for the construction of a wall along the southern border has dipped slightly in the past two weeks, according to a new poll.

The Quinnipiac University National Poll published Tuesday found that 41 percent of respondents now support a border wall, compared to similar survey on Jan. 14 that showed 43 percent approved of it.

Opposition to the wall held steady at 55 percent in the new survey.

Nearly two-thirds of respondents — 64 percent — also said that building a wall wouldn't significantly reduce violent crime in the country. Sixty percent said it wouldn't significantly reduce the amount of illegal drugs in the U.S., according to the poll.

“Voters buy in on better border security. But that wall ... Bad idea,” said Tim Malloy, the assistant director of the Quinnipiac University Poll.

The poll's results were based on surveys of 1,004 voters from Jan. 25 to 28. The poll has a margin of error of 3.7 percentage points.

The poll comes days after the end of a partial federal government shutdown that lasted more than one month. It was sparked because of President Trump Donald John TrumpUS reimposes UN sanctions on Iran amid increasing tensions Jeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Trump supporters chant 'Fill that seat' at North Carolina rally MORE's demand for congressional funding for a border wall.

Trump for weeks refused to sign a bill to fund the government that didn't include at least $5.7 billion for the construction of a wall. He agreed last week to sign a bill to reopen the government for three weeks without wall funding, but has indicated that he may be willing to shut down the government again if Congress doesn't agree to wall funding by Feb. 15.
