America’s crucial midterm election is about 180 days away, but already some important dynamics are emerging. This preliminary analysis can provide us with some direction about what issues, voter groups and national winds may determine victory or defeat on Election Day. With the dust still settling from yet another primary night in West Virginia and Nebraska, here are four takeaways gleaned from available data and polling.
A divergence is developing between Biden’s net approval and the generic ballot for congressional races.
1. Yes, President Joe Biden’s job approval is an important factor in this election, as the president’s popularity has been in midterm elections over the past 50 years. However, a divergence is developing between Biden’s net approval and the generic ballot for congressional races.
For example, in the latest Yahoo News/YouGov poll, Biden has a net minus-12-point approval rating, while Democrats have a 5-point lead on the generic ballot. In mid-August 2010, when President Barack Obama’s approval rating was hovering close to where Biden’s is today, the GOP led on the generic ballot by an average of around 4 points.
2. In addition, Donald Trump’s net unfavorability may be as important as Biden’s. Obviously, it is important for each party to motivate its base voters, as it will be to persuade the large group of independent voters who have consistently been crucial in elections. But digging deeper, a small segment of voters is likely to be key players in the battle for control of Congress and statehouses: voters who dislike both Trump and Biden. Today, that group represents a not insignificant number of all likely voters and a huge opportunity for the party that can capture it.
In the 2016 exit polls, around 14 percent of all voters disliked both Trump and Hillary Clinton, and this group of voters supported Trump by a wide margin. In 2020, voters who disliked both Trump and Biden accounted for only 3 percent of all votes.
