From Gallup:

Obama’s decision to reverse the prohibition on funding for overseas family-planning providers may be the least popular thing he has done so far. This was an executive order that forbade federal government money from going to overseas family-planning groups that provide abortions or offer abortion counseling. Fifty-eight percent of Americans disapprove of Obama’s decision to lift this ban, while only 35% approve of it. The ban on federal funds to these groups was put in place by Ronald Reagan, but lifted by Bill Clinton. George W. Bush re-instituted the ban after taking office in 2001, but Obama has once again lifted it.
