More than three-quarters of mothers and half of fathers in the United States say they’ve passed up work opportunities, switched jobs or quit to tend to their kids, according to a new Washington Post poll.

While it has long been clear that finding affordable, dependable child care is a daily challenge for parents of young children, the new poll provides rare data on the breadth of the problem and how it’s shaping careers for millions of American parents.

The poll also signals that the issue will figure in the 2016 presidential campaign, with about twice as many Americans saying Democrats would more reliably ensure access to child care than Republicans.
