Do not let a win in Iowa, where barely 5% of Iowans bother to spend entire day in a boring Caucus, in concluding winner of Iowa will win nomination.
The winner will be decided in large blue states who get large number of delegates. Republicans in blue states tend to be more centrists. Just look at the senators they send from blue states. Mark Kirk? Jacob Javits? Scott Brown? Pete Wilson? Arlen Specter?
Are you getting my drift? Does Cruz have a chance to carry any of those states?
Santorum won Iowa. Where is president Santorum?
Huckabee won Iowa. Where is president Huckabee?
John Kerry, Barack Obama, George W. Bush, Al Gore,Bob Dole, Walter Mondale, Jimmy Carter might disagree with your assessment
