speeches, the six figure speeches. and she didn't have a very strong reaction to that last night when asked about that, she says, well, look, that's what they're offering and that's what other secretaries of state have done in the past. but he seems interestingly he's got this huge lead, you know, possibly winning new hampshire. we certainly don't know as we saw in iowa until the voters have spokens but he is just going after hillary clinton with everything he's got. >> let's talk about the republicans now. senator ted cruz unleashing probably his harshest critique yesterday of donald trump's campaign. >> reporter: and trump is now saying that he should have won iowa if it weren't for those rumors that ted cruz people pushed forward that ben carson was dropping out. he was not dropping out. and carson has responded to that. but trump is saying that they confused a lot of voters and trump thinks he would have gotten a few more votes, a few more points and won iowa if not for that and that questionable
