I don’t know that I can explain his delivery tonight, but Santorum doesn’t do teleprompters, even for lengthy speeches. It’s one of his trademarks and has often been remarked on by others. When he gave his (great) speech when still tied in Iowa he didn’t use one, although he did read one quote from written notes. It shamed Mitt into taking down his own teleprompters and delivering his standard stump speech, because he couldn’t do anything else without them.
