There has been some interesting research on the correlation between lawyers and gun owner rights. Here is the conclusion:

Lawyers contribute primarily to candidates who vote against gun rights. Most of this money ends up in the pockets of Democrats, who exhibit a heavy bias against gun rights. Interestingly enough, the Democrat party is the one that claims to represent the little guy, while a special interest group comprised of economically-elite professionals encourages Democrats to pass more laws limiting the right of self-defense for people who cannot afford private security guards. It’s time for those who believe in traditional Democrat values to take a closer look at their party.

My own research on a closely related topic supports this conclusion. I'll post the details on my research at a later date.
