Rep. Alexandria Ocasio-Cortez is horrified at what she’s seen on her visit to a holding facility for illegal immigrants — just a week after she voted against emergency funding to improve conditions at what she’d taken to calling “concentration camps.”

This after months when Democrats insisted that talk of a border crisis was just a Trump administration contrivance, and refused to even vote on its requests for funds.

AOC has a great gift for theater, as in her claim that detained women are forced to drink from toilets — which apparently refers to standard plumbing units for these facilities, which hold both a sink and toilet.

This was almost as inspired as her stunt last fall, getting photographed with tears while supposedly viewing kids held in cages — when a wider shot revealed that she was actually looking at an empty lot.

All the outrage is supposed to lead the American public to blame President Trump. Even when Democrats admit that overcrowding at these “camps” dates at least to the Obama era, they pretend the US government is the cause of the chaos.

Yet Washington didn’t tell these migrants to travel across thousands of miles of Mexico to then cross the US border illegally. It’s the governments down in El Salvador, Guatemala and Honduras to blame for conditions there, as El Salvador’s new president, Nayib Bukele, told the BBC on Monday.

If anyone’s encouraging them to come, it’s people out to provoke a crisis — immigration activists who think it will promote their desired reforms; drug cartels that profit from the border chaos; politicians back home, milking their own agendas.

The combination has created a wave of more than 100,000 illegal border-crossers a month, overwhelming the Border Patrol and the agencies tasked with housing, feeding and caring for the detainees.

Yet, though the migrants have been coached to claim asylum under US law, their motives are mainly economic: Undocumented immigrants from these countries have profited from time in the United States for decades, and the courts wind up denying most asylum claims.

The grassroots of the Democratic Party has gone full-bore #AbolishICE. The 2020 contenders are rushing out plans for waving the migrants through, and vowing to provide them with free health care, too. But that’s not US law now, nor remotely what most Americans want — since it would plainly invite far larger waves, from across the globe.

AOC’s theatrics aim to play on American hearts — and distract American minds from her absurd prescriptions. At bottom, she’s just exploiting the suffering she claims to deplore.
