In The Prince he writes:

Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them. Thus it happens that whenever those who are hostile have the opportunity to attack they do it like partisans, whilst the others defend lukewarmly, in such wise that the prince is endangered along with them.

In other words, women are doing well under the old conditions - divorce, child support, etc. So any politician offering to change those conditions will be attacked by women and feminists.

But he will not receive corresponding support from men, even men terribly injured by the current system.
