That’s interesting Rick. I highly doubt Harris would do that. That would blow any chance she has of becoming president. I highly doubt she could win election on her own. I don’t think the Democrats would even nominate her if Biden decides he won’t run again in 2024 or if Biden complete two terms for 2028.
I also agree with rporter. These days there isn’t much different party affiliation wise between the Democratic Party and the Republican Party. It’s independents that decide elections, the popularity or beauty contest is at hand there where charisma plays a huge part in how’ll they vote. That is generally as there’s been election where charisma was in very short supply. These last two Clinton/Trump and Biden/Trump are prime examples. Biden had the upper hand in 2020 because he was much more likeable than Trump and Biden behaved like a grownup/adult whereas Trump was the 4-year-old spoiled brat with his name calling and throwing of temper tantrums. Obama had charisma up the ying yang, he won twice. G.W. Bush didn’t have that much charisma, but he had a down home boy’s charm. It helped G.W. that he went up against two statues in Gore and Kerry totally devoid of charisma. Bill Clinton on the other hand had loads of charisma as did Reagan. They won two terms. G.H.W. Bush lacked charisma, but he lucked out going against Dukakis in 1988 who looked like an idiot riding in that tank. The elder Bush lost big to Bill Clinton.
You can go back to FDR, the candidate with the most charisma has won the independent vote. Sometimes by large margins, other times by a very slim 1 or 2 points. According to Gallup as of 23 Feb 2023, Democrats 29%, Republicans 27%, Independents 44%. Compare that party affiliation to 2006 when Democrats had a 37-31 advantage over Republicans with but 30% identifying as independents.
