re: Do you support local law enforcement being compelled to enforce federal law?

Yep give the money back.

Whether Trump will follow through on all of his proposed immigration reforms remains to be seen. A Trump administration that withholds federal funding – of which Somerville receives $6 million annually – to sanctuary cities will surely do them harm. While federal funding generally makes up only a potion of a city’s budget, cities will feel it most with expenses such as new fire trucks or police cruisers, special education, drug treatment programs, school lunches and other services.

The two largest sanctuary cities in Massachusetts that receive federal funding are Boston, which receives about $250 million annually and Springfield, which, according to the city comptroller’s office, received approximately $83 million in federal revenue last year.
