The candidates running for the Democratic presidential nomination are really getting loopy.

Many are proposing massive government programs that will cost trillions, and even pledging to redistribute wealth. But the issue of the day, at least right now, is helping to get foreigners into the country — illegally or otherwise.

Former vice president Joe Biden is going one step further.

“I respect no borders, and cannot be contained by any walls,” he said in a foreign policy speech Thursday in New York City.

“As president, I will do more than just restore the historic partnerships. I’ll lead an effort to reimagine them, to better meet the challenges we’re grappling with today in the next 20 or 30 years, to keep NATO military capability sharp, while also expanding our capacity to take on non-traditional threats like weaponized corruption, cyber theft, new challenges in space and on the high seas,” Biden said. “No country, even one as powerful as ours, can go it alone in the challenges of the 21st century,” he said.

Biden also criticized President Trump, saying his “erratic policies and failures to uphold basic democratic principles have muddled our reputation and our place in the world, and I think, quite frankly, our ability to lead the world.”

The vice president said in May that illegal aliens in the United States have a right to free health care. “Look, I think that anyone who is in a situation where they are in need of health care, regardless of whether they are documented or undocumented, we have an obligation to see that they are cared for,” Biden said.

“Look, I think that anyone who is in a situation where they are in need of health care, regardless of whether they are documented or undocumented, we have an obligation to see that they are cared for,” Biden said. “That’s why I think we need more clinics in this country.”

Some candidates are even helping foreigners cross the border.

Sen. Cory A. Booker, New Jersey Democrat, last week went into Mexico to help escort five female foreigners into the United States, according to Fox News. He crossed the El Paso, Texas, port of entry into Ciudad Juarez with several immigrant-rights attorneys to help the women get admitted into the U.S. after they had been sent back to Mexico.

In his first international trip as a candidate for the Democratic presidential nomination, former Rep. Robert “Beto” O’Rourke of Texas also traveled to Ciudad Juarez to meet what his campaign called “individuals and families directly impacted by Donald Trump’s cruel and inhumane policies,” The Associated Press reported.

O’Rourke has also advocated doing away with border barriers. As a crisis at the U.S.-Mexico border has exploded — with more than 100,000 entering illegally over each of the last three months — O’Rourke said, “Yes, absolutely. I’d take the wall down.”

“It’s hard to make a rational case for an emergency declaration or troops on the border or any amount of additional border walls or border fencing or steel slats,” O’Rourke said.
