Don’t get up Bill O’Reilly’s Irish. When MSNBC host Chris Matthews said that Texas Sen. Ted Cruz has a “black Irish look” like 1950s Communist-hunting former Sen. Joe McCarthy and O’Reilly himself, the Fox News Channel host took him and his network to task — aiming directly for their ratings decline. “In the last six months..its all fallen apart for MSNBC,” O’Reilly said Thursday about Matthews’ “desperate attempt to get attention” and MSNBC’s recent results. As I reported last month, MSNBC hit its worst total day performance since June 2006. In primetime, the cable news network was down 20% in viewers and 19% in the key adults 25-54 demo from May 2012 to deliver its worst result since December 2007. While FNC is still far ahead in viewership and the demo, the past couple of months have seen the cable gods shine favor on CNN, which has risen to second place while MSNBC has found itself falling to the fourth spot behind HLN. Here’s a clip from last night’s The O’Reilly Factor:
