Answer:
Step-by-step explanation:
George washingtone didn’t have a nominating convention. As the commander of the colonial forces in the American Revolution, he was an easy candidate to select from among the eligible pool of any white man 35 and older, and he won his first two elections without any real competition. After that, there was no clear path for narrowing the pool, so political parties developed their own ways of choosing candidates.
Parties began holding conventions in the early 19th century and presidential primaries in the early 20th century. The convention remained the main way of selecting candidates until 1972, when new rules gave the primaries more power to determine the nominee. Since then, conventions have become a way to celebrate a predetermined candidate, rather than a means of choosing one.
So yes they have changed a lot
