That is true but the vaccines against "wok virus" are pretty effective  :-)   .. when people go to ballot they  leave the noise behind ... 

The reason for the noise is a vertical split   -  on multiple dimensions  ..for example 
-  base is sick of  wars - leadership is for 
-  base  is against Israel - leadership is for 
-  base is tired of inflation - leadership is focused on stock market 
-  base is worried of influx - leadership wants to open the flood gates 
-  base is done with ID politics  - leadership is still pushing the same chords

 I am not judging "right or wrong" on any of the issues I mentioned - all I am saying the party is in total chaos ..  the same thing reflects at the top of the tickets - no credible name wanted to throw in their hat against Trump2024 ... so you have what you have ! I wouldn't be surprised if RFK pulled more popular votes out of dem base than the coronation :-)  

On the other side - you have a party united under one banner. The message is clear  and everyone is aligned  - again no judgement on wrong or right - because no one knows the future ..but the game is not about being right or wrong  - it is about the organization .. better organized wins and is likely to take correct decisions as and when needed ..
