Here are the sixteen possible outcomes of this tree:
- Candidate votes against amendment, amendment fails, candidate votes against bill, bill fails
- Candidate votes against amendment, amendment fails, candidate votes against bill, bill passes
- Candidate votes against amendment, amendment fails, candidate votes for bill, bill fails
- Candidate votes against amendment, amendment fails, candidate votes for bill, bill passes
- Candidate votes against amendment, amendment passes, candidate votes against bill, bill fails
- Candidate votes against amendment, amendment passes, candidate votes against bill, bill passes
- Candidate votes against amendment, amendment passes, candidate votes for bill, bill fails
- Candidate votes against amendment, amendment passes, candidate votes for bill, bill passes
- Candidate votes for amendment, amendment fails, candidate votes against bill, bill fails
- Candidate votes for amendment, amendment fails, candidate votes against bill, bill passes
- Candidate votes for amendment, amendment fails, candidate votes for bill, bill fails
- Candidate votes for amendment, amendment fails, candidate votes for bill, bill passes
- Candidate votes for amendment, amendment passes, candidate votes against bill, bill fails
- Candidate votes for amendment, amendment passes, candidate votes against bill, bill passes
- Candidate votes for amendment, amendment passes, candidate votes for bill, bill fails
- Candidate votes for amendment,amendment passes, candidate votes for bill, bill passes
Since all four candidates oppose an anti-abortion amendment, and presumably will vote against it, we can elide the bottom eight. That leaves eight possible outcomes to explore, as follows:
- Amendment fails, candidate votes against bill, bill fails
- Amendment fails, candidate votes against bill, bill passes
- Amendment fails, candidate votes for bill, bill fails
- Amendment fails, candidate votes for bill, bill passes
- Amendment passes, candidate votes against bill, bill fails
- Amendment passes, candidate votes against bill, bill passes
- Amendment passes, candidate votes for bill, bill fails
- Amendment passes, candidate votes for bill, bill passes
It seems to me that the political ramifications of each of these eight are worth considering — what is the likelihood, what are the consequences, what is the “right” political calculus?
