Update: Despite Bill Shine’s comments below, Sean Hannity announced that Governor Sarah Palin will be a guest on his program this evening, broadcast live from the Republican National Convention .

TAMPA, August 30, 2012, (LifeSiteNews.com) – Four years ago, Sarah Palin gave a rousing acceptance speech as the Republican Party’s vice presidential nominee. This year, she will not have a venue to provide commentary on the 2012 GOP convention.

Palin announced on Facebook that Fox News Channel had canceled her segment on Wednesday night. Fox confirmed she would not appear on the network during the remainder of the Republican National Convention.

“I’m sorry Fox canceled all my scheduled interviews tonight because I sure wanted to take the opportunity on the air to highlight Senator John McCain’s positive contributions to America, to honor him, and to reflect on what a biased media unfairly put him through four years ago tonight,” Palin wrote. “Granted, our honored and esteemed war hero has gone through much more than the liberal media can ever do to him in their efforts to harm this patriot.”

FNC Vice President of Programming Bill Shine said the cancellation was “based on the fact that the RNC condensed the schedule of speeches from four nights to three.” 

The decision came just days after Palin suggested the formation of a conservative third party “is a possibility if the Republicans don’t remember what the planks in the platform represent” during a Fox News interview. In recent days a number of prominent Republicans, from Scott Brown and John Boehner to Mitt Romney, have discounted the importance of the party’s platform, especially its pro-life and pro-family planks.

Palin cited the breakup of the Whig Party in the 1850s as an historical precedent in words strongly reminiscent of those used by Howard Phillips, founder of the Constitution Party.

Her husband, Todd, was a member of that party’s Alaskan affiliate for seven years.

John McCain – who attempted to have the Republican Party pro-life platform amended to include exceptions in the cases of rape, incest, or to save the life of the mother – was invited to speak to the Republican National Committee last night. His speech focused on maintaining an internationalist foreign policy.

Palin was reportedly not invited to the convention, which concludes this evening in Tampa, Florida.

“When the Romney people made sure that Sarah Palin wasn’t invited to the Republicans’ party, the message was clearly sent that Romney blames Palin for the Republican defeat in 2008,” opined Jason Easley of PoliticsUSA.com, a liberal website. “The Romney folks know that she is toxic to the very women and Independent voters that they are unsuccessfully trying to court.”

“Sarah Palin is now officially unwelcome in the Republican Party,” he wrote.
