Trumps criticism of the obviously biased judge does not "force" anybody to be critical of him. Ben Stein certainly doesn't feel so forced for example, and he is certainly no hardened Trump fan. Only the people afraid of the PC police or who were misinformed feel any pressure about it.
There are not wide spread calls for a delegate revolt. Only a few out of touch loons like Bill Kristoll.
Also the delegates are not just pledged to vote for Trump, they are bound on the first ballot per party rules set down before the 2016 cycle started. Sure, in theory the rules could be changed to unbind the delegates, but its on the order of political absurdity of the rules simply being changed to automatically nominate Howard the Duck and move the convention to Antarctica.
This is agi-prop guys. Ingore it.
Well said ; the msm is stirring the pot...
