It’s also worth keeping in mind Democrat sensibilities around immigration have shifted dramatically in the last decade or so. Speeches Obama made on the topic years ago would bring down a firestorm of outrage today.
“We cannot continue to allow people to enter the United States undetected, undocumented, and unchecked” 
“those who enter our country’s borders illegally, and those who employ them, disrespect the rule of the law.” 
- 2008 Democratic platform
 “immigration reduces the wages of domestic workers who compete with immigrants” 
 “the fiscal burden of low-wage immigrants is also pretty clear.” 
 “We’ll need to reduce the inflow of low-skill immigrants.”
- Paul Krugman, 2006
“When I see Mexican flags waved at proimmigration demonstrations, I sometimes feel a flush of patriotic resentment. When I’m forced to use a translator to communicate with the guy fixing my car, I feel a certain frustration.”
-  Barak Obama. 2006
