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.
