If Trump is Responsible for His Rallies, Then Shouldn't Cruz Be Responsible for His Advisors?

Donald Trump has taken righteous heat for the violence at his rallies. Telling his violent supporters that he will pay their legal bills is outrageous. Predicting riots if he isn’t nominated is likely to be taken as a coded message by his supporters. Trump tells his crowds that protesters are bad people and get what they deserve. He does bear some responsibility for his rallies and the general decline in discourse during the 2016 campaign. Some evangelical leaders are pretty upset about it (see the video of Al Mohler and John MacArthur below).
Earlier today a reader sent a link to Steve Deace’s public Facebook page where he carries on the low level of discourse. Given Ted Cruz’s embrace and praise of Deace and Deace’s representation of Cruz, does Cruz have any responsibility to disavow comments like this? Just one will illustrate:

It was Cruz’s surrogate Glenn Beck who called John Kasich “delusional” and a “son of a bitch” recently because Kasich wouldn’t bow out of the race with not a peep from Cruz.*
My point is not that name calling and crude humor doesn’t happen in politics or any other domain as far as that goes (cue Mark Driscoll’s William Wallace III). However, if blame is going to be assigned for the crude rhetoric in the campaign, then let’s cast a wider net. Furthermore, I can understand the passions which give rise to these outbursts. For myself, I am beyond angry at the choices in front of me and specifically worried that my party might actually nominate someone who wants to commit the nation to mass deportation of 12 million illegal immigrants. However, if I ever resort to sexual innuendo and crass name calling, please readers call me out on it.

I want to hasten to add that my objection to Trump and Cruz isn’t primarily a moralistic one. I do object to the gutter politics and rhetoric but the larger problem is their approach to the presidency and policies. They promise things that are never going to happen and act as if we don’t have a legislative branch. I am not sure their followers understand how a bill becomes law. Trump seems like he can wave a wand and it will happen and Cruz has not displayed the skills for compromise, and in fact seems to hold such skills in disdain.
 
*Although not the subject of this post, I also think Cruz has responsibility to correct the errors of those who speak on his behalf at his rallies such as Glenn Beck. Beck’s misrepresentation of history in his stories about George Washington should have resulted in a public acknowledgement and apology from Beck and Cruz.  Beck stopped telling that particular false story only after Huffington Post called him out.
