From Rasmussen:

Support for mandating coverage of the so-called “morning after pill” is lower than support for mandating coverage of contraceptives in general.

The latest Rasmussen Reports national telephone survey finds that 38% of Likely U.S. Voters think health insurance companies should be required by law to cover the morning after pill without co-payments or other charges to the patient. Fifty percent (50%) disagree and oppose this requirement. Thirteen percent (13%) are undecided.
