The left is up in arms over the Supreme Court's recent decision in "Citizens United v. the Federal Elections Commission". But few voices have been louder than those emanating from the echo chamber at MSNBC. It seems that the cable network's talking heads feel that their parent company, General Electric, deserves a special exemption to what should be a blanket ban on unrestricted corporate speech.

First a bit of background for those unfamiliar with the Supreme Court decision. The court struck down in a 5-4 ruling a ban on corporate (or union) spending on political speech specifically endorsing or attacking a candidate for office within 30 days of a primary or 60 days of a general election. It ruled that the ban violated the First Amendment.

Few liberals seemed to notice that in attacking corporate speech they were also effectively undermining their own employers, media corporations who employs them for the express purpose of engaging in political speech. Surely Keith Olbermann and Rachel Maddow would defend MSNBC's right to speak (and spend) freely without interference from the federal government--especially in the run-up to an election when free speech is most important and must be protected.

General Electric (NYSE:GE) is the parent company of the major media conglomerate NBC Universal, which owns media outlets NBC, MSNBC and CNBC. At times that has led to the lines between corporate advocacy and journalism being blurred.

That was certainly the case when GE's CEO Jeff Immelt appeared on CNBC's "Squawk Box" May 20 to discuss the White House meeting of President Barack Obama's 16-member Economic Recovery Advisory Board headed by former Federal Reserve chief Paul Volcker.

Immelt used his platform at CNBC to make the case for a cap-and-trade program to curb emissions - something Obama has called for and one Congressional committee is debating this week.
