Someone should ask Mitt Romney whom he voted for in 2020.
According to the Guardian:
On the night of the 2018 midterm elections, as a wave of anti-Trump sentiment swept Democrats to take control of the House, top Republican Mitt Romney urged Joe Biden to run for president.
“You have to run,” said Romney, the Republican presidential nominee Biden and Barack Obama defeated in 2012, speaking to the former vice-president by phone.
The same night, Romney was elected a US senator from Utah, a post from which he would twice vote to convict Donald Trump in impeachment trials.
Romney’s exhortation to a man then seen as a likely challenger to Donald Trump in 2020 will probably further enrage the former president, his supporters and the Republican party they dominate.
The Biden-Romney call is described in The Long Alliance: The Imperfect Union of Joe Biden and Barack Obama, a book by Gabriel Debenedetti that will be published next week. The Guardian obtained a copy.
