Some of the morning-after analyses of what Rick Santorum's exit from the Republican field means for the 2012 presidential campaign:

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.

Much of the Republican political establishment, many GOP voters and political analysts were telling Rick Santorum that the time had come for him to end his quest for his party's presidential nomination even before Tuesday when he failed to win any of three primaries.

Those calls had only increased by Wednesday as Santorum fell further behind Romney in the delegate count.
