The most likely reason is that Rob Portman did not follow any other senators on Twitter, and only two senators followed him.

comThe second community, shown in blue, is formed by 12 senators, all of whom are Democrats.

The reasonable explanation might be all the 12 senators share the same political stance and are closely interacting with each other.

Another interesting thing is, the second community contains 5 males and 7 females, which means 70% of the whole female senators are in the second community, according to the total of 35 males and 10 females.

That is to say, the second community may be a place where female leadership is more pronounced.

The seven Democratic senators in the third community are — Martin Heinrich (@MartinHeinrich), Micheal Bennet(@SenBennetCo), Joe Donnelly(@SenDonnelly), Tim Kain(@SenKaineOffice), Sheldon Whitehouse(@SenWhitehouse), Joe Manchin(@Sen_JoeManchin), Tammy Baldwin(@SenatorBaldwin).

Among the 32 senators, only three are female.

The third community is a place where male discourse power dominates.
