When was the last time that the polls were right?
Well, for some people, polls are correct if they are favorable to their candidate. If the polls are unfavorable, then they are wrong.
I happen to think most are unreliable and worthless. This is especially true more than a year before the presidential general election. And even at other times I wonder, is someone fudging the results? And who do they ask and where? For example, in my liberal Democrat town, if a pollster were to ask most residents, then yes, that poll would be highly unfavorable to Trump. And as
@The Ghost said, people lie.
The "poll" that really counts is the one where we cast our ballots on election day. Of course, if there is voter fraud, our votes might not count then either.
