WaPo has this take, on Gillebrand's call to abolish ICE specifically (excerpts):

....

In an interview Thursday evening on CNN, the potential 2020 presidential contender said she agrees with escalating calls on the left for getting rid of ICE. “I agree with it. I don’t think ICE today is working as intended,” Gillibrand told CNN's Chris Cuomo.

She went on: “I believe that it has become a deportation force, and I think you should separate the criminal justice from the immigration issues, and I think you should reimagine ICE under a new agency with a very different mission and take those two missions out.”

Notice Gillibrand didn't say that the United States should stop deporting illegal immigrants altogether. She just said this particular agency should stop doing it because it has become too controversial.

That's not far from what 19 ICE agents argued recently in a letter to Homeland Security chief Kirstjen Nielsen that the Texas Observer uncovered. They claim that the drama over deportations is hindering all the other work ICE does, and they asked to have their agency spun off from the main one.

Proponents of abolising ICE don't necessarily want to open all borders to illegal immigrants and let them stay forever. But those are nuances that will likely be completely missed — or ignored — by the president and his allies as they try to cast Democrats as the reason Washington can't get anything done on immigration reform.
