Marco Rubio has criticized Obama on more than one occasion for using a teleprompter. I found it quite humorous that he totally embarrassed himself the other day when as he concluded a speech he found he had forgotten the last page of the speech. It doesn't matter whether the speech is read from note cards, pages of paper or a teleprompter and to suggest otherwise is just mindless ridicule for ridicule's sake. What matters is what the content of the speech is and how it is delivered.
Some days it just isn't worth the effort to chew through the restraints.
