Elizabeth Harrington reports for the Washington Free Beacon that supporters of the movement to extract Great Britain from the European Union are happy to have received some help from President Obama.

Brexit leaders are thrilled President Barack Obama came out against them, because they are seeing a bounce in the polls.

Arron Banks, the British entrepreneur leading a grassroots effort to leave the European Union, said he hopes the president continues urging the United Kingdom to remain a member state, during a trip to Washington last weekend. Banks, the chairman of Leave.EU, met with government officials and think tanks to gain support for “Brexit,” the movement to leave the European Union, when the U.K. votes on the EU referendum on June 23.

Banks said issues of immigration and economics should make Americans invested in whether its oldest ally leaves the EU.

“I think it’s hugely important geopolitically because the European Union is developing into a kind of United States of Europe, and that’s something the British are naturally pretty anti,” Banks told the Washington Free Beacon. “And it’s really come down to the point where most of our laws are now being made in Brussels—65 percent. Our ultimate court is in France and we’ve got open borders to 500 million people. So clearly immigration is a massive issue, it’s not dissimilar to a lot of the stuff they are discussing with Trump, in the sense of [how] some of these issues resonate.”

Banks said the American equivalent of being in the European Union would make Congress in Toronto, the Supreme Court in Havana while having a completely open border to Mexico.

“People are pretty cross,” he said.

Banks said a core issue is being able to return sovereignty back to the British parliament, “so you can sack your politicians when you don’t like them.”
