When is comes to immigration in particular, that simply isn't true. As I alluded to in my comment, Obama inherited Bush's Operation Streamline immigration regime, which was running like a Swiss watch in comparison to the mess we have now. Over the course of his two terms, Obama squandered his inheritance as the progressives encroached. By election season in 2015, the progressive model was being embraced by mainstream Democrats, and was pretty plainly admitting to open-borders aspirations. In my opinion, this more than anything handed Trump his first election victory. If there was one thing that could convince the normies that we need a border wall-- whether literal or symbolic-- it was the sudden realization that the Left was serious about open borders and unlimited immigration.

And of course, not to be outdone by Obama, Joe Biden managed to lose control of the border in a manner that has no precedent in American history, once again handing Trump an easy victory. It's like they wanted to lose another election.

To grasp how radically the Democrat party has moved left on immigration, recall that Obama and Hillary Clinton ran against each other on strict immigration enforcement. Here's my favorite Hillary quote from a 2008 campaign speech:

> "If they’ve committed a crime, deport them, no questions asked. They’re gone. If they’re working and law-abiding, we should say here are the conditions for you staying: You have to pay a stiff fine because you came here illegally, you have to pay back taxes, you have to try to learn English, and you have to wait in line."
