Jewish World Review has a lengthy list of contributors that are (mostly) conservative. At least a few of them have available audio.

Most of specifically Jewish political conservatism originates in religious teaching. Many rabbis have on-line audio and video, but the emphasis will usually be religious and the language and concepts might seem pretty foreign to someone unfamiliar with traditional Judaism.
