I don't vote for pro-choice liberals. Whether they're Rudi or the Beast.
So you and all the rest of the hard liners can abstain and Hillary's minions will get her elected while you sit around because the Republican candidate doesnt represent everything you stand for. There are more issues than abortion and gay marriage.
(1) No Republican candidate is going to propose a constitutional amendment banning abortion, in today's political climate (I wish they would, but the realities of Washington says otherwise).
(2) Overturning Roe vs Wade does not eliminate abortions; It just returns the matter back to the states.
(3) Assuming he runs, Guilani may make a few statements saying he's opposed to abortion (to appease conservatives) but will say that any abortion proposal has to go through Congress anyway.
