Rob,
If an explicitly Christian Pro-Life Party forms, perhaps by that name "The Christian Life Party", you must vote for it.
'Zeolot' has a precedent history.
I will not vote Republican, Democrat, Libertarian, Green, or Communist. If a true Pro-Life party emerges I will consider it - but I will be very skeptical since the Republican party is supposed to be "Pro-Life". I don't want to support another political party that just "tickles my ears".
