Thats withihin three point o hillar meaning they are stattilly tied. Abcs jon karl has the very latest from des moines. Good morning to you, jon. Reporter good d morning, amy. With just four days to go until those Iowa Caucuses, the battle between hillary clintnton and Bernie Sanders is getting heated and personal. Overnighghbefore an overflfl crowd in mason city, io, Bernie Sanders took this shot at Hillary Clinton. My opponent is not in iowa tonight. She is raising money from a philadelphia investmentfirm. Reporter the Clinton Campaign hit back noting that hillary also met with nearly 50 africanamerican ministers from across the coury while in philadelphia. Clinton cled out sanders for his r rent a aacks oner high speaking fees. Senator sanders has started to get increasingly personal me to d ck cheheney last week which, you know, is kin of a low blow. Reporter earlier in the day sanders was back in washington traveling to the white house to meet with the man h hopes to replace. The president and i discussed this morng a number of issues.

He has 13 events betweween now and the caucus. Clinton will actually be doing more campapaign events in iowa than Hillary Clinton. My goodness. Ats what he loves. Jon karl, stand by. Im here withh matt dowd, our political analyst. Yesterday you posed t t queueion on donald trump,ould his refusal to go to the debate be seen as a sign of strength or weakness. 4 hours later. Hissupporters are stiing with him through thick and tn in the course of this. I dont think thats a problem at this point. Its inresting, everybody that opposes donald thinks it was a bad idea. Everybody that supports donald thinks i it was a good idea. At a minimum hes owning the news cycle but poses a bit of a question for fox news, for truru and othercandidates. No empty podium at the debate tonight but how do the moderators and other candidates handle trump witim not on the stage. This is going to bee a fascinating c conversatn because think they mayay talk about trump more now than they d if heas at the debate. I think ted cruz is more dippointed than fox news that because i think ted cruz is now behind donald trump. Ted cruz needs to start worrying ababt marco rubio. Rubio is starting to g gn momentumumumn io. If he isnt careful marco rubio could come up and finish second. You talked about the momentum for Bernie Sanders in iowa right now. But that latest poll out this morning shows Hillary Clinton with a small ad, basically a dead heat, right now in these nal days and you hadhe had that yesterday. He pretty much had to do that after seeming to put on the scale for hillary earlier in the week. Yeah, in the timing was interesting bringing him off the Campaign Trial right before the Iowa Caucuses but t president d to come out and show h he is keeping by his vow that he will be neutral in this race even though clearly the clinton campai believes that if you went into that secret ballot that president obama would be voting for hisormer secretary of state. Matthew, the Clinton Campaign has to worry about deja vu. Into the caucucus eight years ago. I i they l let Bernie Sanders win iowa he will win New Hampshire and then this race totally resets in a different territory than they ever thought. M matthew dowd and jon karl, thanks very much.
