The voters are screaming much more than Trump.
I think it’s because they know two things:
1. It exposes trumps lack of effort and preparation.
2. It seems to be working. There are enough ignorant people out there and plenty of support in the media to propogate the narrative.
It’s like the BS in Iowa where trump lost and opened a two pronged lie offensive. It worked to slow the Cruz momentum and hide trumps lack of campaign skills.
