It's more likely that they would vote for Bernie, doesn't it?
I know that Iowa's more important symbolically than in reality, and that you don't like Cruz, but it's still important that serious non-Trump groupies get to the caucuses and caucus. ^-^
I think less of Cruz than many do. I think he is not electable, due to his extreme positions in relation to the entire electorate. I want a nominee that can win the general, not somebody that merely pleases the fringe of the electorate.
I also question his eligibility, since there is no legal precedent for a President born outside the US.
It pleased Huckabee and Santorum backers for a few weeks when they won Iowa in 2008 and 2012, but it meant nothing in the end. Nothing.
