True, if Cruz wins Iowa, he can survive whatever oddball crap the little out of touch cross over electorate does in New Hampshire.....and go into SC with momentum. If Trump wins NH, which seems plausible, he will also go into SC with good momentum.
SC setting up to be crucial, as is usually the case.
my thoughts....
momentum is in essence hype and hoopla propagated by the media
trump has shown himself able to make positive adjustments to the H&H. thus Iowa and NH will not have the ability to create momentum if Trump doesn’t want them to
the media cannot completely comprehend this fact and so far is unable to make adjustments
