Sometimes it's not about "the numbers" -- it's about sending a message. As the article mentioned:
>Kariv is a veteran of the Israel Defense Forces and the Shin Bet, Israel’s intelligence agency, but he has been horrified by recent events
It's my understanding it's rare to state that publicly, and even rarer to pair it with a political call to action.
I am not Israeli, but soon I too will physically stride into a polling place (rather than mail in a ballot).
I will do this because while I think vote by mail is important sometimes it is also important to teach a certain personality that voter intimidation will not be tolerated.
