He is repeating himself AND adding a little bit more each time. that’s called “staying on message”. You have to look at it from the world of the low info voters and others who only pay attention a few months before an election. To freepers and others who are very engaged all the time, it is repeating, but to others, it may be the first time they hear it and he is consistent. He just happens to be getting a lot of airplay right now so we hear it over and over. :)
Iowans would have to live in a poltical vaccuum to not know Trump is strong on immigration and Vets. He spent too much time on those again. Time to bring some new issues to the fore.
