He's an admitted believer in the so-called constitutional right of abortion. Abortion is most definitely not a constitutional right and had it not been for a handful of liberal activists in black robes overruling the will of the people, it would still be an illegal act most states. There is more, a lot more, but no need to keep piling on. The false flag of abortion rights alone is more than enough to disqualify him from ever gaining the presidency.
You have every right not to accept his position, but the sad truth is that aboerion on demand IS a constitutional right, at at least we must assume that it is, because those men in black robes do have the authority to make the courts start with that assumption. Only that court can change this, absent a formal amendment of the Constitution.
