(FOX NEWS) - Donald Trump’s rivals tried to make the most of their final debate with the Republican presidential front-runner before next week's Super Tuesday II slate of primaries — with do-or-die contests for Marco Rubio and John Kasich in Florida and Ohio, respectively — but whether it changed minds or won over enough undecideds to influence the outcome remains to be seen.
First out of the gate Friday was Trump, who got the endorsement of former rival Dr. Ben Carson, who said he forgave Trump -- "the Christian thing to do" -- for any campaign attacks and praised him as a man whose public image belies his true character, describing him as a far more “cerebral” candidate than he’s given credit for. His endorsement appears to serve as a counterweight to Carly Fiorina coming out for Ted Cruz earlier this week.
At the Miami debate Thursday night, Trump summed up the reality, though, that Florida Sen. Rubio and Ohio Gov. Kasich face.
He said only “two of us” can get the delegates to win – meaning Trump and Cruz — and “two of us” cannot, referring to Rubio and Kasich.
“That is not meant to be a criticism … that’s just a mathematical fact,” Trump said, urging the party to “be smart and unify.”
