Banning members of the press from his rallies indicates either abject ignorance oft the Constitution or his contempt for it. Is that whom YOU want to be president of YOUR country? Selective? Is a Cherrypicker your cuppa tea? Wouldn't you rather have a president who swears to UPHOLD THE CONSTITUTION? EVERY WORD OF IT? Why?
Repugnicans don't typically seek to truncate the first amendment. For them it is a non-issue.
Better to hit them up on their disdain of the fourth, fifth (and, more recently, tenth) amendments instead. Repugnicans never saw a police state they didn't love. :-)
