Nike's latest bet

Nike has just chosen a surprising person to represent the 30th anniversary of their slogan, "Just Do It".  Colin Kaepernick, past quarterback of the San Francisco 49ers, has been a subject of controversy since 2016 when he "took a knee" during the National Anthem at the start of his NFL games. Colin was protesting racial injustice in the United States. In an attempt to discover how this controversial choice might affect Nike's business, Darren Rovelle, a sports business analyst, hosted a Twitter poll. This activity is about the viability of that poll.  What is required to produce a meaningful poll?
