Lawyer said something in passing that piqued my interest

Ok, so I'm in a criminal case for reckless driving and my lawyer is a criminal defense lawyer. We strayed a bit off topic and he commented that most criminal defense lawyers are liberal.

I have zero ways to explore that - this is my first court case since I was 16, I don't know any lawyers and don't have much reason to cross paths with folks like yourselves.

So if you are comfortable sharing your thoughts, do you think this is generally true or is it perhaps a regional thing (as I think may be more the case)? I'm not 100% sure why this would be the case... but it did kind of blow my mind. I had never considered it, but are their different fields of law that attract different political leanings?? Like are all the conservatives in... I don't know, what's a field of law that tramples on people and takes their money?

In any case, I'm a scientist who putters around a lab and this whole field is new to me. Anyone who is up for sharing their experiences, or insight, or perspective I'd greatly appreciate it.

Hope everyone is having a good day.
