Of course there is. For example if there is a candidate who in all respects comports with my economic and social views, and will appoint nobody but conservative judges, but is for mandatory euthanasia of terminally ill people, and he or she is running against a dyed in the wool communist who I think would bankrupt the society in general and my family in particular, I can't vote for either even though the first candidate is in almost all respects far superior and aguably far the lesser of the evils to society at large. However, morally, I can't go there.
I know that Putin lovers like you may have a hard time with that concept but there it is.
