Iowa does not matter to leading candidates. Even if a leading candidate does worse than expected, the setback can *usually* (see Hillary 2008) be easily recovered from in the next primaries.
Iowa matters to second-tier candidates, who can get a big boost by outperforming expectations, or can be forced out of the race by disappointed financial backers.
Iowa is a microcosm of the country we used to be. Then you head to the NE and people get squirrely...Trump appeals to the masses. Like it or not, he does. I see a team of he and Cruz leading us back to where we should be.
Obama will leave a bigger mess than Carter did. It will take a couple generations to undo it.
Look at the ME all these young kids growing up with a new found hatred for us and Israel.
Trump is the short term answer, CRuz and some of the other young men are the long term.
Tell that to Dubya, Jimmy Carter and Barack Obama.
