I don't agree with either as a "model" it ignores the candidates in general. The older/younger younger/older is just one of many different ways tickets have been balanced throughout history, geographically, age, experience, ideology. All have shown abilities to win as effectively as the other
Let's also not forget GWB was 54 when he ran for president, putting him middle of the pack age wise, it was more experience balance, not young/old. Cheney was only 5 years older.
My Statement on the new Model was....
"or the trend of the past 16 years...Less Experience Pres/ more experienced VP.." The whole premise is I am saying the last 16 years & most recent 3 presidential tickets... Have a VP who is FAR more experienced than the President
(I just added that this tends to lead to a VP "less likely" to be the presumptive nominee... as VPs with a lot of experience are often too old 8 years later...to want to jump into the race - as was the case with Biden & Cheney)
