How so?
Gorsuch is a perfectly fine candidate for the Supreme Court. He's a staunch constitutionalist, which is a welcome position to have when your job is interpreting the constitution, and on top of that he's had a very prolific and successful career as a judge prior to his nomination.
There is literally no practical reason to filibuster his nomination; whatever their reasoning is, it's coming off as though it's because Annoying Orange nominated him. It's making the Democrats look like children.
