Liberals have at their disposal three kinds of arguments against confirming Judge Neil Gorsuch to the Supreme Court.
They can say that the mainstream judicial conservatism that he undoubtedly represents is dangerously wrong. A lot of liberals probably believe this. But most people find that argument unreasonable, so few liberals make it.
They can say that Gorsuch should not be confirmed to keep Republicans from being rewarded for their refusal even to consider President Barack Obama’s nomination of Judge Merrick Garland for the same seat on the Supreme Court. But voters didn’t much care about Garland’s plight last year, when his nomination was live, and are unlikely to care more about it now.
This leaves door number three: Liberals can pretend that Gorsuch is a far-right extremist. Many liberals are rushing right in.
