What makes you think she isn't. I literally just typed that she did not vote to directly fund ICE. She voted to fund the Department of Homeland Security.
Here's a list of all of the agencies within DHS. Tell me how she can fund all of them and not fund ICE.
It's absurd to say that she's dumb because she objects to a subagency within a larger federal department. And she didn't vote on individual subagencies, she voted to continue funding to the group.
To put this in other terms. Someone votes to continue funding their local public schools then they say "Elementary School X needs to be closed." Bunch of idiots run out and say doesn't that person realize they just funded that school. Obviously, but you can't not fund 99% of the public schools while you wait to shutter Elementary School X.
People want to cut welfare...but they still want to fund the government. Are they idiots because they fund the government and then state objections to specific programs within that government?
Or should we not fund any of the government while we wait?
