WASHINGTON, March 2 (Xinhua) -- The number of Americans who want more gun control is growing, according to an NPR/Ipsos poll issued Friday.

Three-quarters of Americans said gun laws should be stricter than they are today, up from 68 percent in a October 2017 survey following the Las Vegas shooting, the latest poll showed.

The poll also found widespread bipartisan support for gun-control policies including expanding background check for all gun buyers (94 percent), adding people with mental illnesses to the federal gun background check system (92 percent), raising the legal age to purchase guns from 18 to 21 (82 percent), banning bump stocks (81 percent), banning high-capacity ammunition magazines that hold more than 10 rounds (73 percent) and banning assault-style weapons (72 percent).

However, there was a clear-cut partisan gulf since 68 percent of Republicans favored President Donald Trump's proposal of training teachers to carry guns in schools, compared to just 18 percent of Democrats. Overall, 59 percent of the polled said they opposed to Trump's idea, which was previously proposed by the National Rifle Association (NRA).

In a televised White House meeting with lawmakers on Wednesday, Trump suggested he was open to expanding background checks and possibly raising the age to purchase an AR-15, questioning Republicans' relationship with the NRA.

"They have great power over you people. They have less power over me," Trump told Republican lawmakers at the meeting, "Some of you people are petrified of the NRA. You can't be petrified."

"We see in this study, a majority of Republicans saying that they are supportive of a variety of different gun-control measures, many of which Trump mentioned explicitly in his [White House] briefing," said Chris Jackson at Ipsos.

"President Trump is actually closer to where the Republican base is on the issue of guns than a lot of Republican elected officials," Jackson said.

So far the Republican-controlled Senate has no plans to vote on gun legislation in the near future, though 78 percent of Americans said Congress needs to do more to curb gun violence according to the NPR/Ipsos poll.

Roughly two-thirds, or 63 percent, said guns will be an important factor in their vote in November Midterm elections, the poll showed.

"This data indicates there's actually an increasing energy on the side of gun control," Jackson said, "Given that guns have become very partisan, that may have really significant results in the midterms."

The poll was conducted from Feb. 27 to 28 with a survey sample of 1,005 adults across the country. It has a margin of error of 3.5 percentage points.
