Tuesday could be the last stand for the "stop Trump" movement in the Republican Party. If the real estate mogul manages to win Florida and Ohio and their combined 165 delegates, there is probably no stopping Donald Trump from wrapping up the nomination before the party's convention in Cleveland in July.
Ohio looks like the establishment's best hope. Polls show the race either tied in the Buckeye state or give Ohio Gov. John Kasich a slight edge. He has the backing of the state party establishment and is campaigning on Monday with Ohio GOP Sen. Rob Portman and 2012 GOP nominee Mitt Romney. If all of this is not enough to keep Ohio from Trump, then nothing can stop him.
Florida, which like Ohio is winner take all for the GOP, looks like a near lock for Trump, with polls showing him up an average of nearly 20 points over home state Sen. Marco Rubio. If Rubio pulls off the shock victory for the 99 delegates, it would be yet another blow for the polling industry. The Rubio campaign hopes to run up big numbers in South Florida to counter Trump's strength to the north but Sen. Ted Cruz of Texas has made a late play to try to deny Rubio the win and drive him from the race. He may succeed in doing just that. Cruz has even edged ahead of Rubio in some Florida polls. A third-place finish in the state would be a devastating embarrassment for Rubio.
