State of the Union viewership is driven by partisanship
Biden might like to imagine that his State of the Union address is not only a chance to lay out his agenda for the country but also an opportunity to change a few Republican minds.
However, odds are that Biden’s audience mostly consists of people who already agree with him about most things: Democrats.
In his first two addresses to joint sessions of Congress in 2021 and 2022 (the first technically wasn’t a State of the Union), polls found that around half of the viewership identified as Democrats, while around one-fifth to one-quarter identified as Republicans.
There isn’t anything unusual about this sort of partisan gap, though: Historically, people who identify with the president’s party are more likely to watch the State of the Union, based on polling since Bill Clinton’s presidency.
In other words, the State of the Union can sometimes verge on a pep rally, with the president working to animate his supporters in the room and at home with applause lines. Now, Biden also made bipartisan and even nonpartisan overtures in an effort to appeal across and beyond party lines. But as the trend in the chart above suggests, far fewer Republicans are likely watching his speech than Democrats.
