This is completely the fault of hillary, podesta, the DNC, Soros etc. By paying for birddoggers, agitators, people to disrupt and start fights at Trump rallies etc. without punishment they normalized this behavior by their supporters. If Comey wasn’t so intent on keeping his job and Lynch wasn’t so bereft of integrity this would have been stopped before it became this bad. Pandora’s box has been opened, the demons are out and I don’t think they will ever be put back in the box no matter who the republican candidate is. There were shades of this behavior when Bush the son became president but it has become much worse and I only see it getting worse with time. At some point the US is going to need martial law around every election if the democrats do not win.
