There is no doubt that mixed in among the estimated 10,000 innocent men, women and children in the caravan of Central American migrants marching north in Mexico toward the U.S. border are bad people who want nothing more than to kill and injure Americans.

“What we do know is that terrorists have highlighted for many years the loopholes in our border security,” Department of Homeland Security (DHS) Secretary Kirstjen Nielsen told Fox News Martha MacCallum Thursday night. “What we do know is there are criminals as part of this flow. We do know there are gang members as part of this flow.”

Nielsen added that U.S. Border Patrol officers, every year, apprehend about 3,000 “special-interest aliens” — immigrants from countries compromised by or associated with terrorism.

Similarly, Derek S. Maltz, a former special agent in charge for the Drug Enforcement Agency’s Special Operations Division told Fox News host Laura Ingraham on “The Ingraham Angle” Thursday evening that “these organizations don’t just wait. They actually are planning to get people here in this country to do very bad things. That’s the bottom line.”

But try telling that to Democratic leaders.

Here are five who don’t seem to have a clue:

1.) House Minority Leader Nancy Pelosi (D-Calif.) opposes every immigration reform proposal President Donald Trump has submitted to Congress. But the one she most opposes is the one that would be a huge obstacle to illegals trying to cross into the U.S.

“We have to do something other than building a wall … In my view, it’s immoral, expensive, ineffective, and not something that people do between countries,” Pelosi (pictured above center) said earlier this month at Harvard’s Institute on Politics.

And one more thing: Keeping drug dealers, gangbangers and terrorists out of America, according to Pelosi, is Trump’s “manhood” issue: “But in any event, it happens to be like a manhood issue for the president. And it’s wrong, and I’m not interested in that.”

2.) Senate Minority Leader Chuck Schumer (D-N.Y.) thinks the caravan isn’t a national security problem. He thinks it’s just a ploy by Trump and other Republican leaders to distract voters from their intense desire for more Obamacare bureaucrats telling their doctors and nurses what to do.

“Mitch McConnell, Paul Ryan, and Republicans in Washington are making a mess of our health care system, causing premiums to increase and care to decrease while threatening to gut protections for pre-existing conditions. Democrats are focused like a laser on health care and will not be diverted,” Schumer (above left) said in a joint statement with Pelosi.

3.) Rep. Julian Castro (D-Texas) was Secretary of Housing and Urban Development (HUD) under former President Barack Obama. Now he’s thinking about making a run for the 2020 Democratic presidential nomination, but a few more disconnected statements like this one about the caravan might put an end to such hopes.

“The caravan is only highlighting Trump’s failure on his signature issue, which is why he is cooking up conspiracies and blaming Democrats. Trump is a failing president, and the sense that this failure must be checked is stronger with voters than the fear that the president is whipping up over the migrant caravan.”

“So I think that people can see through fearmongering and trying to pit people against each other and scapegoating of the folks with a failed policy, and it is so convenient that this comes up two weeks before the election.”

4.) Sen. Mark Warner (D-Va.) is the ranking Democrat on the Senate Select Committee on Intelligence. He hadn’t said much at all about the caravan — until Friday, when he suddenly wondered about the “unusual timing” of the marching migrants.

“The timing of this caravan, much larger than anything we’ve seen before — I’ve asked and we’re trying to get the intelligence community to see, why now?” Warner said on CNN’s “New Day.” “Why at this moment in time? Who would this benefit if it’s suddenly in the news?”

Warner was evasive. “We’ve never seen a caravan of this size. Usually there’s been smaller ones that have been about safety. This one seems much, much larger, and at an unusual time.”

When anchor John Berman pressed Warner to be more specific, asking, “Are you suggesting that it was ginned up for political purposes?” Warner was evasive. “All I’m saying is, we’ve never seen a caravan of this size. Usually there’s been smaller ones that have been about safety. This one seems much, much larger, and at an unusual time.”

Warner should see number two above.

5.) Rep. Joe Kennedy III (D-Mass.) is the grandson of Robert F. Kennedy and great nephew of former President John F. Kennedy. Mention the caravan to him, and he sees visions of his family’s Irish ancestors fleeing the Potato Famine in Ireland in 1845.

Here’s some of what Kennedy (above right) wrote Thursday in Time magazine: “Today, thousands more families fleeing unspeakable violence at home are marching towards our southern border. And all this government has summoned to meet them is cruel words, course threats and the specter of more innocent children forced to watch their parents dragged away.”

“This is the trauma and torture that dark forces of nativism, supremacy, and prejudice have brought to bear in a land that staked its name on brighter, better things: equality, dignity and freedom,” he also wrote.

Maybe Kennedy is right: Mexican drug dealers, MS-13 murderers, terrorists, and hardened criminal child predators just want to be equal, dignified and free … to sell drugs, terrorize Americans, and stalk little kids.
