I believe this to be non-sensical. So there are no pro-choice republicans? There are no pro-GunControl Republicans? How about pro-gay republicans?
Just because it is in the party platform doesn't mean these people won't vote their constituents' wishes (more and more unlikely), what is perceived publicly popular at the time, their personal ethics, their religious beliefs, or what their lobby interests tell them to vote for on condition of later payment.
Just as you point out that there is almost never a pro-gun control republican, you must also allow that there are the occasional pro-gun democrats.
