If you're going to make a protest vote for someone who will never be elected, it had better reflect your moral views, not some abstract political theory.
Unfortunately there is no Catholic Monarchist Party :scratchchin:
I'll probably just stay home.
It's better to vote Constitution if they are seriously pro-life in their rhetoric, because they recognize natural law and the actual law.
However it probably won't make any difference.
The last Constitution party candidate, Chuck Baldwin, had a great essay about "a wasted vote."
Voting for the loser is, in some sense, a wasted vote, especially if it was a "lesser of two evils" vote.
I think people who typically vote Republican in states like California and New York should start voting third party when the issue of the election is not in doubt.
