"Political beliefs" are not necessarily applicable to Judeo/Christian/Biblical values. But they aren't necessarily not applicable either. You cannot believe that killing the unborn is okay and still be in line with scripture. You cannot believe that homosexuality is not immoral and still be congruent with the Bible. Things like that.
That's not to say that a Republican cannot take an immoral political stand, but if you read the party platforms, one holds to biblical values and one does not. That's just the facts on a purely platform basis.
