Speculation is swirling around the identity of a "mystery speaker" expected to address the Republican National Convention on Thursday night.
HuffPost's Jason Linkins relays background:
On the Thursday night schedule for the Republican National Convention, there is a big old space marked "To Be Announced" and the speculation is going today about who might be the super secret "mystery guest." According to Sara Libby of Talking Points Memo, "top advisers to Mitt Romney's presidential campaign" -- including Romney veep-vetter Beth Myers and senior aide Eric Fehrnstrom -- say that they "have no knowledge" of who it might be.
Republicans have managed to inject some drama into their convention - amid widespread complaints that national conventions have become stagey, boring multi-day commercials - by allowing speculation to run rampant about who will share the stage with Romney Thursday. Organizers built up the buzz by reserving a special guest spot on that evening's program in between a performance by "American Idol" alum Taylor Hicks and a speech by Florida Sen. Marco Rubio.
Fox News and Townhall have reported that actor Clint Eastwood is headed to Tampa and is the "mystery speaker," according to their own respective sources. Whether the outlets are right remains to be seen.
Sarah Palin has also been floated as the unnamed individual expected to speak on Thursday night.
