Donald Trump's playbook appears to be pretty simple. Internationally, he threatens big tariff increases if countries don't do what he wants. Domestically, he threatens to cut off federal spending if states and cities don't do what he wants.
This is of dubious effectiveness in the case of tariffs and of dubious legality in both cases. In any case, his latest attempt at extortion is aimed at sanctuary cities:
President-elect Donald Trump’s advisers are discussing how to unilaterally strip federal resources from Chicago and other Democratic-run cities if they refuse to participate in deportations of undocumented immigrants next year, according to three people familiar with the conversations.
....Trump vowed mass deportations during his campaign — eliciting fierce pushback from some Democratic mayors in “sanctuary cities” and governors in blue states, some of whom are already promising to defy the president-elect’s pledges. He tried to slash funds to those jurisdictions in his first term, but with only limited success, and any similar effort in his second term could also run into roadblocks.
"Not a cent," said Vivek Ramaswamy over the weekend. That's unlikely in the extreme, but Trump could make states and cities waste hundreds of millions of dollars in legal fees along the way.
If we were dealing with someone more rational, you might figure a compromise could be worked out. Maybe the funds at risk could be limited to those related to immigration. And perhaps Trump could agree that the most important thing is for cities to turn over violent criminals for deportation, not the poor schlubs who just happen to be in the wrong place at the wrong time.
That would make a big difference. Most sanctuary cities refuse to use local police to do the federal government's bidding, but they don't withhold every speck of cooperation. In particular, they generally hand over violent criminals to ICE for deportation when their sentences are up. You can see this in the results of a study from the National Academy of Sciences:
The top panel shows what happens to illegal immigrants with no criminal convictions. When a city adopts sanctuary policies, deportations go down significantly.
But the story is entirely different for violent criminals: There's no change before and after. Woke or not, everyone agrees it's a good idea to deport genuine bad guys.
It's also worth noting that most places don't adopt sanctuary policies just to thumb their noses at Donald Trump. They do it because maintaining law and order is easier if illegal immigrants aren't afraid to talk to the police. A highly public sanctuary policy assures everyone that they can call for help or answer questions without fear that a cop will decide to haul them in and turn them over to ICE. You may disagree on balance, but there really is a reason for this stuff.
