The threats of violence on twitter are from the usual impotent loonies. Also, it started after the Canadian sponsored Sikh terrorists put out a video on You Tube threatening all Hindus in Canada with death. Video is not taken down yet.
Soros has already promised $1 Billion to unseat Modi last year. The Globalists who want Gandhi to win have been "pouncing" every year since 2005. Ending with lower seats every time.
This time I note that they engineered unification of opposition parties to take out Mr. Modi.
There will be a major effort IMHO and they will try to create extreme incidents like January 6th in the USA to get what they want.
