Let's say a friend of yours is running for some executive-branch government position (governor, mayor, etc) in your jurisdiction. You love your friend, and have a lot of respect for his intelligence and leadership ability, but your political views completely differ from his on almost every topic. Do you...?
Publicly support and campaign for him, but vote for someone else
Vote for him, but refrain from offering him much public support or campaign help
Both vote for him and campaign for him
Neither vote nor campaign for him
