Ridiculous article. DeSantis has no intention on focusing on the 2020 election any more than he has to. He was asked a question, who won, and gave the correct answer, Biden was sworn in, therefore Biden won.
Trump is the one who not only wants to stay focused on 2020, but needs to. It's part of his sympathy routine. Which, one has to admit, is working quite well.
So DeSantis was probably targeting that a little, but it won't be a focus of his campaign. He's made that clear, his campaign is strictly about bringing the strong conservative values he's helped implement in Florida, to the nation.
How many opuses for you thus far . . . ?
