Cable news ratings, April 15, 2010: Check out the highlights, and see the full ratings below:

• The bad news continues for CNN’s 7pmET program John King, USA. The program reached new lows in both the A25-54 demographic and total viewers Wednesday, but the demo was so low it tied for the worst ratings on CNN in any hour. With just 53,000 demo viewers, the only other program that low was the 4amET repeat of Campbell Brown‘s show (and the only other program on all of cable news with less demo viewers was MSNBC’s NoonET hour – with 52,000).

• The top show was Bill O’Reilly‘s 8pmET program for FNC. The top non-FNC show was Nancy Grace‘s 8pmET show on HLN in the demo and Keith Olbermann‘s 8pmET show on MSNBC in total viewers.
