Marriage should not be a government matter.
The problem with both the Republicans and the Democrats
is power and control.
Both want to control your choices,
your behaviors, your life.
Libertarians want to leave you alone to make your own decisions.
Good or bad, right or wrong, moral or immoral,
as long as you don't commit a crime against a person
(you know, robbery, battery, murder, etc.),
what you do and with whom you do it (consenting adult) is no one's business.
