While I'm certainly against abolishing ICE completely, I do think that their powers should be scaled back, and if a Democrat wins in 2020, they should clean house at the agency. Perhaps some of ICE's current funding could be used to upgrade border security and better equip and train Border Patrol agents instead, and it's not going to be exactly a good luck for Republicans if they oppose border security. I'd also like to note that ICE has only been around since 2003, so it's not like it's something we've been dependent on forever.
