Why Did The Teleprompters Fail?

The teleprompters failed several times at the Republican convention. Most notably during Sarah Palin's speech. Did anyone notice? No, she just kept right on speaking, "from the cuff" with one of the best-known remarks, the one about the difference between a woman and a pit bull being lipstick, was NOT on the script. Could this be because those with the responsibility to keep them “up and running” are union members? Remember, union members (not necessarily all of them) promote the Democrats over everybody else. It’s very suspicious when teleprompters fail so often in one event (Former Mayor Rudy Juliani and Sarah Palin at this one convention). It would be very easy for the people responsible for keeping them working to “forget” to do “one small thing” so they’d fail. (Just common sense)
