Free speech doesn’t permit you to lie about people in public. It’s called slander and libel, and we have very good laws against that. In fact, mot Freepers bemoaned that Bush did NOTHING against the lies perpetrated by Harry Reid and the Dems for six years, which destroyed his administration. About time someone pushed back on this crap.
Free speech DOES allow one to tell lies in public about others, within the constraints of 5 or 6 types of lies. Moreover, suits on defamation as to public figures are very difficult to win.
Furthermore, if Katich's ad is anything like the Club for Growth ad that featured Donald is his own words advocating for universal health care, tax increases and eminent domain that Trump threatened to sue Club for Growth over, then it is certainly not libel and slander. And if the Donald wants to sue his opponents over words or actions that he has said then that is wrong and he is no friend for free speech.
