I've worked those positions and all sorts of shenanigans happen ..you' be surprised. I actually had a news journalist take a photo of me persuading a voter and celebrating that he changed, but the shot was taken clear over from a parking lot ....I never saw him take the photo....til it hit the front page the next day.
It was used at a time you had to be so many feet away from the voting stations....a good thing I was "legal".
It’s one thing to persuade another candidate’s supporter to vote for your candidate, based on positions, etc ... BUT it is quite a different matter to allege that the other candidate is quitting the race, when such “fact” is actually not confirmed, at best, and a willful fabrication at worst.
