Rudy Giuliani, that’s who. Or at least that’s what his campaign is saying after he spent the night and morning at a St. Louis hospital having a battery of tests performed. But excuse us for being a little skeptical that a simple case of the flu is the cause of his lengthy stay. Remember the last big election in which Giuliani was supposed to run against Hillary Clinton for a senate seat in New York? He ended up getting prostate cancer. As his poll numbers continue to slide, watch out for a recurrence. The mind-body connection just might be getting the best of him.
