No leftist has shot at Trump or plotted to.Trump has issues and I will not refute that. I will, however, point out that the guy you say has issues which make him unqualified for office, isn't trying to assassinate a presidential candidate to keep him from being elected to that office. So, if we're going to talk issues, then let's not hide from the fact that so far the violence has come from the LEFT.
There has been no leftist violence that mattered in this country since the 1970s.
