Did Nixon run around the country obsessively talking about how he was defrauded in 1960? No. He won in 1968 mostly based on policy (and the failures of his predecessor.)
Trump, OTOH, has made "I was cheated!" the centerpiece of hsi campaign.
Andn candidates in 2022 who ec hoed that lost bigly. If Trump wants to win, he needs to focus on his policy record and not on his 2020 loss.
Maybe if Nixon had, the cheating would have been nipped in the bud.
There isn't an issue more important than free and fair elections. But DeSantis his supporters and the Republican establishment is perfectly fine with the fraud that occurred in 2020. The Republican establishment was complicit in it.
