The suffix “-bot” (for"robot”) is often added after a politician’s name to show deluded, robot-like followers. For the 2007-2008 U.S. presidential campaign, followers of Ron Paul were sometimes called “Paulbots” and followers of Barack Obama were sometimes called “Obamabots” or “O-bots.”
 
The “-bot” suffix in politics dates to at least October 1992, when listeners of conservative talk show host Rush Limbaugh were called “Limbots.” A December 1992 post used the terms “Clintonbot” (after Bill Clinton). “Gorebot” (after Al Gore) and “Dembot” (after Democrat, probably with a nod to the older term “fembot”). To be called a political “-bot” is usually derogatory.
 
     
Urban Dictionary
Paulbot
Freedom and personal liberty loving online supporters of Ron Paul were given this name by close-minded individuals who only follow main-stream media’s propaganda and lies. The close-minded refuse to believe that Ron Paul has more support than landline phone polls reflect, and therefore any online entity that supports Ron Paul must be a ‘bot’. Fortunately for America there are millions of people who support the only hope for America’s future, Ron Paul.

A lot of Limbots seem to have trouble with this tricky “if/then” construction, so let’s try to make this very, very simple.
