I mean there is a conversation to be had that it would be different. The debate performance would normally shift votes, but didn't. The assassination attempt would normally shift votes "hugely" but it hasn't shown. I think people knew who they were going to vote for before we knew the nominees. No new information was going to change that.
I would just argue that with everything being "unprecedented" we shouldn't rely solely on old election data. Trump won in 2016 because he ran a different campaign, yet Democrats still seem to want to run old style campaigns.
Glade you asked. YES. Former Presidents Harry Truman, Richard Nixon, Jimmy Carter, George H. W. Bush and George W. Bush all had approval ratings below 30%.
"When comparing Biden to his predecessor, the latest number is just below the highest approval rating (44%) Donald Trump received in our polls during his four years in office...."
