And theyll tell you ted cruz needs the win here in iowa to carry the momentum he has seen in the last few weeks, donald trump could use a win here just to show he has some staying power beyond the enthusiam and the excitement that hes been able to sort of drum up , the big test for him is to turn that enthusiasm to turn out you know for the caucuses, the first time caucus goers so thats the republican side. Itll be very interesting to see where senator marco rubio lands too tonight, hes able to come in third place or second place it would be huge for him. For the democrat side i think Bernie Sanders really iowa most people accept that heget the win in New Hampshire its right next store to vermont but i think he needs the iowa win to fuel him beyond New Hampshire as they head to the south. Secretary clinton would love a win here in iowa i dont think she wants a repeat of eight years ago but i think he needs it more.

We go live now to abc9s lukas voss. Lukas theres a little bit of a difference in the process between and the dems, could you tell us more . Lukas jenna, indeed. Its a little bit more complicated than with the republicans. I am here with tim bottaro. With the Woodbury County dems. Just what does that process look like . Bottaro so lukas, the way the caucus on the democrats side works is a bit different to say the least, bottaro democrats will gather at their precincts, and form groups amongst themselves in support of which candidates they feel represents however there is a catch if one of the candidates cannot pool 15 of the room, they will be deemed not viable and must realign with another group in support of a different candidate or they precints may be a school or a local church, but for some, theyre getting a more personal, intimite experience.

These two keys aspects. A candidate may lose more than election as a whole. A new american centurny and yet still missing alsaska and hawaii.
