Real answer? Pick a battle and commit to it. That means allying with folks who agree with you—or have an incentive to agree—on your one issue with whom you may strongly disagree on other policy or even moral positions. This doesn’t need to be a permanent alliance, after all, just a transactional one to achieve a goal.
Just be careful not to turn into a 1-issue voter. There's a lot of people out there that vote for the candidate that agrees with them on the one issue they consider the most important... and they ignore the substantial amount of evil that candidate does that's _not_ that one issue.
