the republicans kicked off their first debate of the primary season. the top ten were there. they did not hold back. many of them targeting donald trump. he was quick to strike back. >> to the wee hours this morning, one candidate getting strong reviews wasn't on the main stage with the top ten. carly fiorina scoring huge for her performance. how could this first debate shake up the rest of the race? let's begin the debate coverage with chief congressional correspondent, dana bash live in cleveland. good morning. >> reporter: good morning. that is just one of the many way this is debate was like nothing we have ever seen before. i believe that my phone is still lighting up with tweets from donald trump going after the moderators in this debate because he was not happy with how it went or what they said about it afterwards.
