Oh for crying out loud....go away already. You know nothing of the US or how it works.
In truth there's many of the “World Citizens” online doing just that.
There's “Machines” as this all over the states and Internationally. Just depends on were they have them focused.
Needless to say we have the “Clinton Machine”..The “Obama Machine”..The Islamic Machine”... and many others that tap the college campuses where kids like to “feel” significant by signing onto where ever their political interests are....and more often than not they gravitate to anything on the social media to do the work.
Everything has a certain rhythm to it....you can tell when kids are out of school...and college kids when date night hasn't materialized for them. The entire social networks “rhythm” shows who is on as the tempo of posters changes.
Same when there is a particular political event and the true activists, hired and otherwise, begin commenting. Nestled among them all are those who love to simply "create" chaos situations that aren't real to begin with.
