Sen. Bill Cassidy (R-La.) told CNN's "State of the Union" Sunday he does not believe that former President Trump will, or should, be the Republican nominee for president in 2024.

What he's saying: Cassidy pointed out that "over the last four years, [Republicans] lost the House of Representatives, the Senate and the presidency. That has not happened ... since Herbert Hoover."

Cassidy said he believes the GOP should listen to the voters who they did not attract in the past election. He added that he wants to push successful policies in the next elections, and that he is concerned that the GOP won't win if they continue to "idolize" Trump.

• "If we plan to win in 2022 and 2024, we have to listen to the voters. Not just those who really like President Trump, but also those who perhaps are less sure," said Cassidy. 

Asked if he believes Trump will be the next Republican nominee for president, Cassidy responded, "Our agenda does not move forward unless we win. We need a candidate that cannot only win himself or herself, but we have to have someone who lifts all boats. 

• "And that's clearly not happened over the last four years, so that's a theoretical that I don't think will come to pass."
