No. I’m speculating on circumstantial grounds that it was staged by Hillary to make it look like Bernie was playing dirty tricks on poor little victim her. Sanders will be forced off message by a deluge of planted questions, and have to spend time condemning the ridiculous deed and denying any relationship to Mr. Decals. This is exactly what a rival candidate wants on the eve of an election, when there’s not enough time left for the truth to emerge.
When Arthur Bremer shot George Wallace in 1972, Nixon ordered operatives to rush to Bremer’s address before the FBI or cops arrived and plant McGovern campaign literature. Hillary is a thousand times more devious than Nixon. If she didn’t do it, she wishes she had.
Wow! I agree with your speculation.
Hillary is definitely devious enough to try that.
