The NFL is the rare thing that brings all Americans -- Democrats and Republicans -- together

The NFL is the most popular sport in the US -- and it isn't even close.

(CNN)Almost everything in our world today is divided along political lines. Whether it be something as important as a life saving vaccine or something as simple -- and you would think would be non-partisan -- as what TV programs people watch or jeans people wear, everything seems to be polarized along partisan lines.

That's what makes the NFL standout. While the NFL should perhaps worry about the youngest of fans, football is by far the most popular sport in America. It's a sport whose popularity cuts across political and racial divides.
Witness the ratings for the Dallas Cowboys vs. San Francisco 49ers playoff game on January 16. More than 41 million people on average tuned in for the game, while 50 million saw the Cowboys lose on one of the most atrocious play calls I can ever recall. This was, of course, merely a first round playoff game.

    To put that 41 million in perspective, the most highly-rated, non-football television broadcast in 2021 had a little less than 34 million people tune in. Keep in mind that program -- the inauguration of President Joe Biden and Vice President Kamala Harris -- was broadcast across more than a dozen channels.
      And while most of television is struggling to keep viewers in the streaming era, the NFL has actually been gaining viewers this year. Over the course of 2021, 75 of the top 100 programs were NFL games.
        But this isn't just about television ratings, it's about interest at large.

        The NFL is king in the US

          A 2021 Ipsos poll asked American adults whether they were fans of a sport or not. A majority (51%) said they were fans of professional football.
          No other sport (pro baseball, pro basketball, pro hockey, pro soccer, college basketball or college football) even cracked the 40% mark. In fact, only pro baseball and college football even broke above 30%.
          Pro football is the only sport that a majority of Americans (51%) said they were fans of.
          While different pollsters have found differing levels of support for professional football -- depending upon question wording among other factors -- it's the top sport in any poll.
          Moreover, there's no sign that pro football's popularity has waned when examining Ipsos polling.
          In 2007, the same 51% of American adults said they were a fan of pro football.
          When you dig in deeper, you can see why the NFL does so well: it's popular across the political spectrum. Among Democrats, 51% said they were fans of the NFL. Among Republicans, it was 50%. A majority (55%) of independents indicated that they were fans of the NFL.
          You can see the same thing when you look at Google searches. The NFL is not only the number one most searched league in America, but there is not a statistically significant relationship with the level of search interest by state and how that state voted in the 2020 election.
          In other words, the states Democrat Joe Biden won search as much about the NFL as the states Republican Donald Trump won. That's not the case for any other major sports league in America: MLB, MLS, NBA or NHL.
          This may be surprising given what has occurred over the last five years between Trump and the NFL.
          Trump blasted the NFL in 2017 following players kneeling during the national anthem. In 2020, Trump and his allies again went after the league after more players knelt in the aftermath of George Floyd's murder.
          Kneeling during the national anthem as a protest against social injustice became a large political issue in the US from the time Colin Kaepernick (seen here with then teammate Eric Reid of the 49ers) began the trend in 2016.
          NFL leadership backed the protests in 2020, while they did not in 2017. Perhaps, they realized Trump wasn't ultimately making much of an impact.
          Indeed, just like now, at least 50% of Democrats and Republicans were fans of the NFL in the 2007 Ipsos poll.

          Racial divide in NFL fandom?

          It also doesn't appear that there is more of a racial divide among NFL fans than there was prior to 2017.
          In the Ipsos poll, 51% of White adults said they were NFL fans, which is the same as overall figure. Black adults were somewhat more likely to be NFL fans at 62%, though in the grand scheme that is a far smaller racial divide than we see on many issues in America. For example, Black adults were about 40 points more likely to say they were NBA fans than White adults.
          When Ipsos asked about professional football fandom in 2007, 54% of White adults said they were fans of the NFL. This is well within the margin of the error of what the 2021 Ipsos polling found.
          If there is one warning sign for the NFL, it's how young people feel about the league. Fears over concussions may be playing a role in the fact that about 100,000 fewer high school boys played football at the end of the 2010s than at the beginning of the decade.
