All summed up.
redstate.com - Democrats are waging a soft war to keep power through illegals and trump should only buckle down

First, violence:
...violence is a narrative creation machine that, when framed properly, can make those assaulting and destroying seems like freedom fighters and the police trying to keep the peace as oppressive foot soldiers of a dictatorial regime. It also serves a double purpose of intimidating those around them into compliance, so you get a rallying cry from the media and silence from those actually being affected.

This violence over deporting illegal aliens, especially violent criminals, is happening at the encouragement of the left who is trying to make this an issue based in xenophobia, racism, and heartlessness.

This is 100% how it works, especially in blue cities. Disagree with Antifa? They'll dox you and issue threats. Maybe even assault *you* directly. Or pay your house a visit.

On illegal immigration. Bolding mine:
If you know anything about Democrats at all, you know they ultimately care about one thing, and that's power. If the illegal immigrants actually posed any real threat to it, they would've helped Republicans shove them out the door years ago, and our border would be one of the most secure in the world.

But illegal immigrants do actually help Democrats, at least indirectly.

democrat leaders can be the ultimate sociopaths: People are merely tools to be used for a purpose. In this case that purpose is power for...democrats.

Enough fentanyl over the border to kill every man, woman and child in America? So what.
Human trafficking? Drugs? You're a racist, bigot.
On and on.

Bu the bolded part nails it: if illegals were something the democrats couldn't use, the southern border would have a 100 foot high electric fence along its entire length and be patrolled by armed Predator drones. But it's not.

And how do illegals help democrats?
If you've ever wondered why Democrats are so staunch about sanctuary cities, it's not because they're virtuous or willing to help the oppressed. It attracts illegal immigrants, filling out the population, allowing for redrawing of district lines, and potentially giving them a little more power in Washington as these districts vote blue.

It's a long-game strategy, but the census is done every ten years with the next one coming up in 2030. Democrats wanted the illegals it was practically shooing in to saturate parts of America, especially urban areas, giving these Democrat-heavy locations more weight.

That's right. They don't even need to vote - federal dollars can be routed right back to the local democrat party machines for democrats to allocate to other democrats. It's a Ponzi scheme that for some reason national Republicans have tolerated for decades.

Until now.

ICE raids will continue in blue cities. The stakes are too high not to.
