You have to decide what those issues are for you. What do you think disqualifies a person from holding public office? I believe that the endorsement of the right to kill unborn children disqualifies a person from any position of public office. It's simply the same as saying that the endorsement of racism, fraud, or bribery, would disqualify him - except that child-killing is more serious than those.
