Nowhere near like Iowa. Only 7 days from now.
Not sure why you think NH is so important? It only has 23 total delegates compared to 30 for Iowa and all of those delegates are awarded on a proportional basis. Unfortunately, NH is so liberal compared to the rest of U.S. that Rubio, Bush, and Kasich are polling much better in NH than in most places. So, best case scenario, Trump may win NH, but even if he wins in a landslide, Trump will only win a handful of delegates due to the high number of candidates that will still do well enough to receive at least some proportional delegates.
Besides, NH is a joke because no Republican will win NH in the general election and there isn’t enough delegates at stake in NH. Cruz would be smarter to just skip NH and spend his time in SC and super Tuesday States where Cruz can easily beat Trump.
