If that's your choice, please vote for a third-party candidate. A race in which Clinton beats Giuliani 52% to 48% will be remembered as a race where pro-abortion candidates received 98% of the vote. A race in which Hillary Clinton gets 43% of the vote, Rudy Giuliani gets 30% of the vote, and pro-life 3rd party candidates get 25% of the vote (with a few percent to other third-party types) will be remembered as a race that should have been an easy win for the GOP if the GOP nominee hadn't been a pro-abortion extremist.

If Giuliani wins the nomination, my objective will be to ensure that neither major-party candidate receives a majority of the vote. A third-party vote will be the clear and obvious rational way to try to promote that outcome.
