The overwhelming reason women seek abortion is unplanned pregnancy.  The way to effectively reduce the incidence of unplanned pregnancy is through the provision of effective contraceptives.  And that doesn't include condoms, which don't do much to reduce the incidence of unplanned pregnancy.

Back in the 1970's there was almost unanimous agreement between Republicans and Democrats that the provision of contraceptives to poor women was a matter of public health.  We also went through decades of states slowly mandating contraceptives in health insurance - a real recognition of the importance of contraceptives to women being better able to plan their lives so the family can better thrive.

There is also the matter of contraceptives and sterilization being life saving for woman who are told either to delay a pregnancy or not to have another pregnancy  in order to protect her own life or health.  

Yes.  Not including contraceptives in health insurance blocks access to them and even kills.
