kendis and reena. the fog behind me here in cleveland describes the state of the republican race, hazy, but there are enough delegates at stake today to turn donald trump and hillary clinton into front-runners to likely nominees. florida and ohio are the biggest prizes but i can report that there are other states voting today that could really make the difference. it's here, the day that could be a critical turning point in the race for president. >> this is the place i want to wing. this is going to do it. >> reporter: gop front-runner donald trump was in the winner take all state of ohio overnight. attacking the governor. >> kasich cannot make america great again. can't do it. >> reporter: the stop trump movement is in full effect. >> ts country is not about us tearing one another down. >> reporter: rivals spent election eve season on the recent violence at trump's valleys. >> look, a bernie sanders sign, don't worry, you won't get beat
