What sways voters is the message coming from Trump. People are up to their eyeballs with political correctness and the apologists for moslems. Trump is telling the punters what they want to hear. Whether they would vote for him in a presidential race is another matter.
Trump is a sad commentary on the State of the Republican/Conservative "Union" public in the USA.
Remember that the right wing in Germany were also told what they wanted to hear, by Hitler. Trump is using similar propaganda methods and Goebbels' principle of the bigger the lie, the more people believe it.

With all great deceivers there is a noteworthy occurrence to which they owe their power. In the actual act of deception they are overcome by
belief in themselves: it is this which then speaks so miraculously and compellingly to those around them.
