Donald Trump's win/loss column in last night's "Super Tuesday" Primaries made the upcoming Republican National Convention a little more contentious.
Trump, 69, easily won Florida, scooping up all of the state's delegates while ousting Florida Sen. Marco Rubio in one fell swoop. But he lost Ohio's delegates to Ohio Governor John Kasich.
The Donald would have easily locked up the Republican presidential nomination last night if he'd won both Florida and Ohio.
Now Trump is forced to contend with Texas Sen. Ted Cruz at the national GOP convention in July -- if Cruz can pick up enough delegates by then.
Knowing the GOP nomination is still not in the bag, Trump urged his fellow Republicans to throw their support behind him.
But Republicans are hesitant to back Trump, citing his controversial stance on immigration and his dangerously divisive campaign rhetoric that encourages violence at his rallies.
"Millions of people are coming in to vote. We have a great opportunity," Trump said from his Palm Beach, Florida resort, Mar-a-Lago, where he watched the returns on Tuesday.
Rubio -- who called Trump last night, but Trump didn't answer the phone -- quickly endorsed Ted Cruz on Twitter.com.
Cruz tried wooing Rubio's supporters over to his side, saying he's the last Republican standing who has a chance to defeat Trump.
But Trump has a significant lead in the race for delegates, with a total of 621 over Cruz's 396 delegates.
Kasich has only 138 delegates and virtually no chance at winning the nomination.
A total of 1,237 delegates are required to win the Republican nomination for president.
