Pence's social views are awful but he's way more competent and controlled.
Which is why he's less desirable. Pence's agenda is equally as bad (if not more so) for the poor and minorities, and the fact that he's semi-competent means that he'd be more likely to implement such an agenda successfully.
A good comparison to Pence is Theresa May. Various naive Remainers were glad that she (rather than Boris Johnson) became prime minister as she is supposedly a sane and competent individual. As it has turned out, we are more likely to have a Hard Brexit under her than we would have done under Johnson.
