Trump and Biden ads on Facebook and Instagram focus on rallying the base

The campaigns of Donald Trump and Joe Biden together spent US $65.8 million on social media advertising between June 1 and Sept. 13. With these ads, which amount to about 30% of both campaigns’ spending, the candidates are trying to mobilize voters – find supporters and then spark them to get involved.

Biden has maintained a fairly consistent national polling lead of around 7 to 8% since mid June, but Trump’s standing in the race has tightened in certain key battleground states. For example, Biden had a polling lead of approximately 7% in Florida mid June, but his lead has dropped to 1.8% as of September 29. Has the Trump campaign changed its advertising strategies between mid June and September? By looking at the Illuminating 2020 data, we see that there is a re-balancing of ad strategy taking place, as both campaigns are trying their best to find their “sweet spot” of message type targeting potential voters in important battleground states.

An Introduction to the Illuminating Project

Illuminating is a computational journalism project that empowers journalists covering US political campaigns. The Illuminating data helps journalists see patterns and changes in how candidates address communicate to voters over time. If candidates are spending millions of dollars to micro-target voters on digital media, then someone needs to improve transparency and hold them accountable, explains Dr. Jennifer Stromer-Galley, Principal Investigator of the project.
