Um... No. You don't understand my post. Polls are statistically irrelevant and only a tool to generate a sheeple response and discourage an electorate from becoming informed voters. They are statistically irrelevant, whether it be a general election or primary.
Vote for the candidate that will best represent you--Period! The only "poll" that counts is the one on election day when the votes are tallied.
