There are many people who are single-issue voters, which means that they will vote for (or against!) a candidate based on one issue and one issue only. Suppose a politician wants to earn votes based on single issues: Issue 1, Issue 2, and Issue 3.

By publicly supporting issue 1, the politician gains 127 voter but loses 154 . By publicly supporting issue 2 , the politician gains 350 voters but loses 83 . By publicly denouncing Issue 3 , the politician gains 306 voters but loses 158.

By publicly taking those stances, what is the politician's net gain or loss in number of voters?
