There are other things I wish Democrats were better about, such as the 4th Amendment, but they all agree on blanket NSA snooping. Same with the 6th & 8th Amendments are far as torture and never charging prisoners. Capital punishment; drone wars. Same with press freedom, both sides go after journalists. Same with protesters, both respond to people attempting to exercise their constitutional rights with a militarized police force (unless it's white people with guns, then it's perfectly fine to protest any way you like.)
