President Trump is waging a battle against the coronavirus to recapture one of his most important demographics: the voters aged 65 and over who came out for him in droves in 2016 but have since soured on him due to the pandemic.

On Friday, Trump told seniors at a campaign event in Fort Myers, Florida, they would be “first in line” for a coronavirus vaccine, assuring the indoor and largely maskless crowd that he was “moving heaven and earth” to deliver this before 2021.
