evidence: "Abolish ICE" sounds simple and straightforward. It's short enough to fit on a bumper sticker — as does "Build the Wall," or "Abolish the IRS." It symbolizes Democrats' opposition to Trump's immigration policies, particularly the separation of children and parents at the border. It's a shorthand way to remind lawmakers and the public that Democrats don't like how the president has demonized immigrants — whether they entered the U.S. legally or not. It also expresses the fear and outrage among immigrant communities who feel that ICE is terrorizing their neighborhoods. [...] Many Democrats think that turning the debate away from Trump's immigration policies and back to a fight over which party is stronger on border security is a loser for Democrats. It's why so many Democratic lawmakers refuse to jump on the "Abolish ICE" bandwagon. Even Vermont Sen. Bernie Sanders dodged the question, saying only that he wanted to "create policies that deal with immigration in a rational way." Illinois Sen. Tammy Duckworth said abolishing ICE wouldn't accomplish anything, since even without the agency, Trump would still be setting immigration policy. Although Warren and Gillibrand sided with the "Abolish ICE" push, California Sen. Kamala Harris, another possible 2020 contender, did not. Harris said she wanted to "critically re-examine ICE and its role." Many Democratic strategists were asking why — just when the Democrats were winning the immigration debate — they should adopt a slogan that could backfire on them going into the midterm elections.
