With alexander hamilton lyrical analysis.

in paragraph 3, thomas jefferson refers to alexander hamilton as "the brother". based on their relationship, what is happening here? is it the same as calling someone "pal" when you're not really their pal? is the mere fact that he's using a colloquialism rhetorically significant?

I'm not completely sure whether it was used in a way to be passive aggressive towards Hamilton himself. I completely understand why it can be seen this way though I'm not entirely sure whether or not it's made to sound that way towards him. 

To put the actual question into light though, Jefferson is an opponent of Hamilton. They constantly fought over the ideals of America and both voiced their opinions loudly. Even in the song The Election of 1800 it can be quoted that Hamilton "[had] never agreed with Jefferson once", which in itself shows their relationship with one another.
