If you are an elected official you are sworn to uphold the US constitution and the State constitutione even if they are diametrically opposed to the torah failure to do so is grounds for removal.
While toievah marriage is not in the US or NY State constituion, Legalized Abortion IS in the NY state constituion and you are legally obligated to uphold that law not matter what any one else says (If you disagree, then dont run for office)
