When NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health asked parents and caregivers in our new poll whether getting a good night's sleep is important, families overwhelmingly told us that sleep is a high priority.

If New Jersey Gov. Chris Christie was hoping for a return invite to the big CPAC convention this year, he probably should have thought of that before he bad-mouthed House Speaker John Boehner a couple of months back.

Christie was incensed by the House's failure to pass a relief bill helping victims of Superstorm Sandy, which hammered New Jersey and the rest of the Northeast last autumn. In typical Christie style, he did not pull any punches.

The fight over reauthorizing the Violence Against Women Act is now behind us. But like much of what happens in Washington, the process wasn't pretty.
