Updated at 2:23 pm: Rick Santorum's daughter, Bella, is expected to be released from the hospital by Monday evening given the improvement in her condition, said Alice Stewart, spokeswoman for the former senator's campaign.
Assuming her release goes as planned and Santorum, who took a break from his campaign to tend to his daughter and for the Easter holiday, returns to the trail, that would clear the way for the Romney campaign to resume its negative advertising against Santorum.
