>> denise: here's a live look crocker park in westlake some of the businesses evacuated earlier today when propane tanks caught construction site. the fire is out now. be sure to watch tonight at 6:00 how the explosion impacts the american greetings headquarters being built at crocker park. >> dan: like we always do at 5:30, time to talk politics. tonight may be the last stand for candidates to stop donald trump's march to the nomination. >> denise: four candidates will meet in the last debate before they vote tuesday. ryan nobles is live at the university of miami with a big preview of the night ahead. hi, ryan. >> reporter: hey dan and denise.

pressure tonight is on marco rubio. he stakes his entire campaign on winning in the state of florida and collecting the 99 available delegates and polls show that is unlikely. >> if you elect me -- >> as marco rubio's chances to capture marco rubio dwindle the florida senator is openly questioning his tactics specifically the personal trump. >> my kids were embarrassed about it. if i had to do it again i wouldn't. >> rubio's last stand is florida holding several rallies and ads of his super pack filling television airwaves. >> he is capable of doing it. he can be an excellent debater and he needs to do it tonight and convince the voters of florida he is still viable. >> ohio governor john kasich is fighting to win his home state. polls show he has a narrow lead over donald trump and kasich picked up the support of urban

state football team. as for trump, if the past is any indicator regardless how he performs in the debate tonight his support will remain solid. >> i think this will be much different. i may be wrong but i am far and away the frontrunner t. will be softer and i will be ready. i think marco will be a different person. marco has been mortally wounded. you know, questions will marco even be there. >> reporter: after tonight it will be left to each campaign's ground game as ballots are cast in each state and the republican nomination potentially hanging in the balance. >> reporter: for a long time we talked about how the candidates in the race may be hurting marco rubio from being able to establish himself as the closure opponent to donald trump. now that question is being raised in ohio where rubio's support could keep john kasich from perhaps winning his home state. here in florida it is ted cruz

to score that knockout punch that takes rubio out of the race for good. dan and denise. >> denise: so much at stake next tuesday. ryan we heard a reporter accusing donald trump's campaign manager of physically assaulting her at a recent event. what's that all about. >> denise, this is a growing controversy on the campaign trail right now. it has to do with michelle fields, a reporter for the conservative web site which is a pretty positive news outlet for donald trump. they covered him pretty favorably and she was at an event and attempted to ask trump a question and felt someone grab her from behind to the point she was bruised. she didn't see the person who did it. a reporter from the "washington post" ben terrace clearly saw it and said it was cory, the public campaign manager of donald trump's campaign. he put out a statement saying it wasn't him and he actually

overselling this a bit saying in the past she has talked about being attacked covering the occupy wall street controversy. so for bright bart's point they called for them to step down and calling on him to fire him and dan and denise if he were to step down it would be a major shake up to his campaign. he is one of the driving forces of the operation. >> will it ever end? ryan nobles. thank you for your time, sir. >> dan: keep it right here for continuing coverage of campaign 2016 and get the latest on the candidates every day on cleveland 19 news at 5:00 or download our free mobile app and get updates on the go. >> we do have breaking news that's come down. the c.e.o. and coo of the wounded warrior project have both been fired.

vehicles and arrested 7 suspects in lorain and two in florida. >> it was a complex case. these guys are high level traffickers and getting multiple kilos of heroin and cocaine in from out of state and breaking it up and selling it in lorain county. >> dan: nice work here. investigators with the ohio bureau of criminal investigation and attorney general's office the suspects. they are hunting for five more in the lorain area. we will let you know more on the case. >> denise: tonight learning more on an f.b.i. raid in bay village centering around child pornography and exploitation. agents served a warrant on the $1.5 million home on lake road. we checked with f.b.i. officials, no word yet on any arrests or charges. >> dan: severe storms forced thousands from their homes in

>> the principal asked to see more photos and the verdict is out whether morris' daughter can wear that to the dance. >> that was a $500 dress and had us curious just how much going to the big dance cost these days. we found in some cases teens or parents can spend more than $1,000 on prom. according to visa, the average cost of a prom-posal was $324 just to ask someone to the dance. adding up money spent on dresses, tuxes, limo, flowers, pictures, events before the actual dance in 2015 it was down from the previous year. we have a treat for you. we want to you take a look at this picture.

in an excellent opinion piece in the "new york times" emma rauler makes the case. iowa and new hampshire are 90% white. ohio more closely matches the demographics of the nation. it is racially diverse and culturally mixed with big cities, small towns and rural areas. we are a swing state with a balance of republicans and democrats and doesn't cost too much to campaign here. media costs are reasonable giving underfunded candidates a fair shot. but it probably won't happen. parties put penalties in place for states that move primaries up and cutting delegates and our own secretary of state is on the record against it. still it would have been nice to have a chance to vote for a wider range of candidates if we wanted to. instead we have to take what's left after 30 other states have had their say. ohio first primary would be

shows us what happened. >> the video merits another look. a fire near the construction site 2, 1,000-pound propane tanks started the explosion. >> one ruptured and blue through the building and caused the other to blow from the building. >> workers tell us they heard a hissing sound. >> a few minutes before the explosion we heard rumbling and didn't think it was thunder. the windows shook. and you could smell gas. >> other workers took to their cell phones in a parking garage to call loved ones to let them know no one was injured. workers and shoppers compared notes. flames came out of the propane tank and heard explosion. >> the remnants of that on the other side of the american greetings building look at the
