Your graph shows what many of us are saying. Trump was not expected to win Iowa. He finished better than expected.
If no “harm” was done, why the “apology”.
Actually the graph shows Trump winning Iowa till the election. Which I don’t know what you have been saying but Trump says he was winning in the polls until “Cruz cheated”.
As the graph shows there was no harm. If I bump into you in the street, even though you don’t need emergency medical treatment, I apologize.
