Are most judges hacks?

[Attorney General, Senator-Elect, & Former PPT Dwarven Dragon]

Not in the sense that most congresspeople are, where unless it's something that really matters to their district/state, they just do as their party leader tells them without question.

However, in the sense that most judges will generally always rule Liberal or generally always rule Conservative whenever the statute or constitutional provision is ambiguous?  Yes. But even here, generally is the key word. There will always be the weird case, where due to odd facts or exceptionally bad oral argument, the judge will not take its ambiguity to the ideology they usually do. Largely due to differences in the specifics of their profession, these 'edge cases' don't really exist for politicians.
