As we know, DC is the land of 47, and 47 is the 15th prime number, thus the 15 rounds of voting.
DC = 47
Republican = 47
Democrat = 47
Government = 47
Authority = 47
President = 47
White House = 47

Also, Hakeem Jeffries became the first black member of Congress to lead a party. Again, he has the same August 4 birthday as Obama, a man who once took the White House at age 47, with the 47th Vice President, Biden, who went on the become President after 47 years in DC.
