Perhaps the best answer to the question would be to ponder how we ever managed in the times before polling was so widespread and the results available so instantaneously.
Did the absence of numerous daily poll results cause voters to be more apathetic? That’s absurd. Obviously not. And the same would be true today.
But unforttunately it’s too late to close Pamdora’s box. People would be outraged.
At least they did manage to (years ago) curtail the TV results of exit polling in the East being broadcast on TV or radio until the polls had closed in ALL of the time zones because that had caused some folks to stay home thinking their vote was superfluous cuz they figured their candidate was so far ahead. For unlike many other types of pre-election polling, exit polling has proven to me quite accurate.
But there really is no practical way to put the genie back in the box for polls prior to election day itself. People just won’t stand for it.
Ya know…that thing about freedom of speech and all :)
