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. >> this 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 up at my rally. >> one difference between this and a donald trump rally, i'm not asking anyone to pump you in
