Network television snubbed last week's Obamacare announcement, leading some to believe the "liberal" media's love affair with President Obama may be over.

Dr. Brandon Rottinghaus at the University of Houston says there are a couple of things at play here: the president is deep into his second term, and his popularity is in the cellar.

“Its the case where the public is less enamored with him as they once were, its the case too that the policy is very complicated and most people don't understand it,” he tells KTRH News.

And the networks don't like presidents using them as a soap box.

“Its a bit of a dicey situation because in practice the government owns the airwaves, so they can't necessarily close the door and say no, but they can offer some different scenario,” says Rottinghaus.

He points out Presidents Bill Clinton and George W. Bush were snubbed by the networks from time to time.

“Having a president take a victory lap on network television may alienate some viewers,” says Rottinghaus.  “This is not a great scenario for the networks, they don't want to put a president on who is not popular and who is talking about a policy issue that may not be popular either.”
