 John Norris is an Iowa Democrat who's led election campaigns in that state. We reached him in Des Moines. John, as we're speaking, we're hearing that the U.S. president is planning on staying in this presidential race, planning on continuing his campaign. From where you sit, what are the odds that he'll actually step aside? Oh, what are the odds? Well, the pressure's not going to back off. It's going to continue to increase. So I think the odds will continually go up.
