"How can people ignore Trump lies?"  

Because they are so disgusted with the Republican established politicians and the Democrat established politicians and because they have been trained to expect ALL politicians of both parties to continually and constantly lie about anything to get re-elected?

The Trump voters don't seem to me to be FOR Trump; they are against the lying, grafting, greedy politicians who are in charge.   

Trump has not 'played' to the Republican base like a 'real' politician always has.  Bernie did not 'play' to the mainstream or even the center of the Democratic party. 

I think voters are tired of being 'played' and Trump, warts and all, is not an establishment 'player'.  I think he will get more votes for not endorsing Speaker Ryan, for example,  than he would get if he did endorse him.
