Don't tell that to the Obamamedia. They'll brand you a nonbeliever.
"... that I will faithfully execute the office of the president of the United States" is a split infinitive. Then again, so is "I, name, do solemnly swear".
W.H. Taft and Herbert Hoover mangled the swearing in ceremony as well. Which is funny, because it's not the only point of comparison between Hoover and Obama. Both came to office in the grip of an emerging depression and both wanted to spend their way out of it. Both went into the White House overstating the importance of media relations... OH DEAR!
